Criminals have kidnapped Seargeant Miller's daughter Cheryl and threaten to kill her if he doesn't do what they say. And under no circumstances is he to tell anybody. But both Alf Ventress and PC Mason soon suspect that something is wrong. Protesters demonstrate against the French politician Michel Dubois who is at a conference in the area. He is said to have been a Nazi collaborator during the war and Special Branch fears there may be an attempt on his life during the conference and asks the police for backup. The gunman may be the mysterious Frenchman staying at the Aidensfield Arms - or are the people holding Miller's daughter involved? Aunt Peggy is not feeling well and Nurse Cassidy can only tell her to see a doctor. But although Peggy thinks she has one one foot in the grave already she is very reluctant to take such a drastic step.

The old crook Albert Hallows - also known as "The Professor" or just "Prof" - has escaped from prison and returns to Aidensfield. He has a score to settle with the police - they arrested him for organizing burglary on a big scale in the village. He also tricks Bill and Mickey, 2 local boys, into helping him. There is a big charity dinner dance and Joyce Jowett is representing the council together with Oscar Blaketon. Or at least that was her idea. But Oscar is away on a golfing trip, so Dawn "persuades" Geoff Younger to go in his place. She promises to teach him ballroom dancing for the event. Carol Cassidy and Joe Mason have finally realized the feelings they have for each other, and he asks her to the dance following dinner at a posh restaurant. Terry Maxton is an old friend of Aunt Peggy and he is looking for local craftsmen to supply his furnishing stores with pottery. Peggy is convinced there is good money to be made and talks David into making primitive pots of clay - with very explosive results.

It comes as quite a shock to Carol Cassidy, who is an orphan, when one of her childhood friends turns up in Aidensfield claiming that she not only has found Carol's mother, but brought her along too. Barbara Gresham is a young, single mother of a new-born baby. She has been abandoned by the father of the baby and finds it hard to cope with her life. Nurse Cassidy and PC Mason tries to help her, but maybe in vain. Hermione Worthington reports her dog Hercules missing and Sergeant Miller promises her that the police will make every effort to find it. But finding chief constable Worthington's dog is a lot easier said than done. Bernie Scripps has received a car full of chimney sweep equipment as payment for a funeral, and since the village is in dire need of a chimney sweep David borrows the van and equipment to earn enough money to have his taxi repaired and he and Dawn tries their luck with chimney sweeping. That too is easier said than done.

A stranger collapses on the lawn of Ashfordly Hall. He is called Mickey Todd and has been beaten up pretty badly, but is very reluctant to talk to the police. Later Nurse Cassidy sees a pregnant, young woman in the village, who also shows all the signs of a thorough beating, and patches her up. Is she the victim of the same assailant? At least she belongs to the same group of traveling hippies as he does. PC Wetherby is doing some private investigating of his own and discovers that his wife is having an affair. He takes it out on Lord Ashfordly's game keeper Frank Kelly who is found dead the next morning with his throat cut. But Kelly may also have had a clash with the hippies who falsely accused him of assaulting Mickey Todd. David has to fight the competition from another taxi company and also has problems with his own taxi. It turns out that his taxi was sabotaged, and Aunt Peggy is sure that the owner of the other company - Ma Barker - is behind it.

The police had a tip-off and searches the home of Big Frank Batley. His wife Tina claims that one of the police officers has stolen 400 pounds during the search and the money is found in DS Dawson's car.Convinced of her innocence PC Mason risks his career in an attempt to prove it. A lady in another village has died and specifically requested that Bernie Scripps handles her funeral although there are other undertakers much closer to her home. He is shocked to find out that she was an old girlfriend of his and the love of his life - and that they have a daughter Bernie knew nothing about. She was adopted after her birth and Bernies asks Oscar Blaketon to help him find her.

Les Hepplewhite is the leader of a brass band. He has high hopes for the band to regain the Wallace Cup at the upcoming contest. The same has Bill Bugde the leader of a competing band. But there is more behind their enmity than just rivalry over a trophy and the police has to step in when several members of Hepplewhite's band end up in hospital with food poisoning. Dawn is completely swept off her feet by Jonny Leigh who pulls up at Bernie's garage for some petrol. He invites her to move with him to Paris, but the other villagers think things are happening too fast and Aunt Peggy asks her to wait - at least until Gina returns from Liverpool where she has gone to see her family. The heat is on between Joe Mason and Rachel Dawson after he saved her career, but it takes its toll on the relationship between him and Carol Cassidy. Especially after Carol discovers that Rachel has spent a night with him at the police house.

Bob Berisford was a haulage contractor who was involved in a bit of smuggling to keep the company from going bust. After his death his partner in crime Frank Carter wants to continue the arrangement and pays Bob's widow Evelyn a visit. When she refuses her life is threatened. Nurse Cassidy hears about the threats and asks PC Mason to look into it. Soon there is a lot to look into, but he doesn't get much help from Evelyn Berisford who is much too scared to talk. Tomasz Bukowski has come all the way from Poland to Aidensfield to look for a woman he fell in love with during the war, and Oscar Blaketon offers to help him. Bukowski repays him by playing the pub piano. Chopin and Beethoven may attract new customers, but they surely also keep the regulars away.

Three children are exploring the garden of a sinister, old house near Aidensfield when the youngest of them, Peter, suddenly disappears. The whole village takes part in the search. The police concentrate their efforts around a mysterious van that Gina saw racing by just as the two elder kids pass her and PC Wetherby in the street; the police fear the boy has been kidnapped. Luckily he is soon found in a well near the old house, and a major rescue operation is launched. The rescue draws nationwide attention and soon Aidensfield is invaded by journalists from all over the country- including the prominent Sheridan Ralph who is very upset when he can't get a room at the Aidensfield Arms. Aunt Peggy does not hesitate to take advantage of the situation and offers him a room at her place - for at small fee of course. This decision is one she soon finds reason to regret since he is a very bothersome customer. Oscar Blaketon has other concerns than the rescue. He has noticed signs of a growing attraction between Gina and the newly divorced PC Wetherby-signs that don't go unnoticed by Sheridan Ralph either. But there might be a much more interesting story to tell when suddenly gun shots are fired from inside the old house, and it is determined that the house is inhabited by an aged and mysterious man.

A group of Taoist monks is stranded in Aidensfield when their bus breaks down on the way to a Taoist monastery near Middlesbrough. But their presence is a thorn in the side of Councillor Jowett who tries to raise a united front against them. Things don't get better when one of the monks is very ill and is taken to hospital. People fear he suffers from TB, which notorious burglar Terry "Non Stick" Tinniswood supposedly also died of the very same morning. Tinniswood's widow Rosie is especially nervous, because her two children Julie and Eddie were in the monks' bus nicking a gold statuette. Chips off the old block so to speak. DS Dawson has got a tip that stolen antiquities have found their way to Ashfordly. Some of them turn up in Mr. Brigstocke's antique shop. The police lock the shop and take possession of the keys, but when they come to search the place the next day some candlesticks have gone missing. Carol Cassidy is sad because, although an adoption agency has traced her mother, she passed away several years ago. PC Mason offers to lend an ear if Carol needs somebody to talk to.

A cat burglar is causing the police endless worry. He is targeting the wealthy houses of the area, and PC Mason suspects the window cleaner Tommy Hugget who has form, but his wife Betty gives him an alibi. However Mason is convinced that they are hiding something. Major Giles MacLean makes quite an impression on Carol Cassidy when he asks her for directions to Ashforly Hall. The major is on his way to his regiment reunion i Edinburgh and takes his lordship up on his offer to stay a couple of nights. But he too is the victim of the cat burglar. Aunt Peggy is outraged when David finds a young woman camping out on his field - without paying, but changes her tune when she discovers that the woman is her old friend Sofia. And she cannot get them hitched fast enough when David and Sofia feel attracted to each other. It is hard for Bernie to mind both the garage and the funeral parlour and he looks forward to Rosie's return from Australia. But not even her family has heard from her for several months, and when her sheep-shearing friend Mick turns up in Aidensfield asking for her Bernie and her father fear that something has happened to her.

DS Dawson and PC Mason go to Australia to find out what happened to Rosie. They are joined by Carol Cassidy who wants to search for her brother whom she has never met. Dawson and Mason locate Rosie's and Mick's last employer Mrs. Patterson. She sacked the young couple after Mick beat up Rosie in a row, and nobody has seen the young girl after she left town on the bus the following day. But Mason has a feeling that not everybody is telling everything they know. Back in Aidensfield Sergeant Miller has some questions for Mick who is still in the area. Meanwhile Carol finds out that her brother is called Daniel, and she puts an ad in the paper. This puts her in contact with a Doctor Cunningham who claims to know Daniel, but the doctor also has ulterior motives.

The search for Rosie continues. Mick MacDonald is no longer a suspect since PC Mason and DS Dawson have discovered that another young blonde woman - like Rosie - has disappeared in the area. All of a sudden, Carol Cassidy - also a blonde - has disappeared too. And to top it all, a stranger turns up in the town asking for her.

The teacher Jim Osgood is an advocate for iron discipline at the school in Ashfordly and does not abstain from corporal punishment. PC Mason gets involved when Osgood treats the pupil Gary Bell so rough he ends up in hospital. But Mason's hands are tied because neither the boy nor his parents will make a complaint. Furthermore Osgood attacks his colleague Wendy Kelshaw for rejecting him and intimidates her into silence. Oscar, Alf and Bernie are organizing a trip to London for the entire village. But Aunt Peggy is short of cash and sees no reason to go. Things do not get any better when she finds the tramp Ernie Dunn dead in her barn.

A car crashes on the road to Aidensfield. The driver Ellen Ferguson is badly injured while her husband and daughter get off with only minor bruises. PC Mason is sure that she was speeding, but her husband Lennie denies that. But there might be more behind it than that because Nurse Cassidy notices at mysterious man who frightens the daughter Trudi. Shortly after another stranger turns up at the hospital asking for Ellen Ferguson. Only he calls her Phillips and not Ferguson. David wins some money and uses them to buy an old Jeep which Bernie will help him restore. But it turns out that it is not any old Jeep when they find Field Marshall Montgomery's beret in it.

There is counterfeit money in circulation in Aidensfield - and lots of them. The money was made by a gang run by Jim Bly, but neither Bly nor his girlfriend Ruthie Abbott were ever captured, and DS Dawson thinks they may be in the area. Sergeant Miller gets a surprise visit from his wife. Her train broke down just outside Ashfordly and now she has been left stranded. But the good sergeant is none too pleased to see her. Especially not after she has been caught shoplifting. And she is not making things easier for him. Bernie reads in the newspaper that his big idol Judy Garland got married in London and plans to settle down in a British country house - maybe even Yorkshire. And indeed an American woman moves into one of the cottages with her husband. She calls herself Judy Dean, but soon everybody knows who she really is - or do they? Anyway Aunt Peggy cannot help cashing in on it.

When the attractive newcomer Vivienne Mackay is murdered suspicion falls on the backward George Ashton. Normally he wouldn't hurt a fly, but he got mad at her when she pushed him accidentally. But also her fiancée Dominick Billingham is in the picture since he had a row with her at the Aidensfield Arms the night before. PC Mason also has to take care of her son Scott, because Mason's mother was murdered too. Dawns cousin Vince intends to sell hot dogs and leaves his van in her care for a couple of days. Thus he will miss the Ashfordly Cup final which draws a lot of spectators and Dawn decides to use the opportunity to make some extra pocket money. She allies herself with David and that does not suit Aunt Peggy who has planned to sell backed potatoes during the match and as usual has "volunteered him" to lend her a hand.

Harry Brown has an accident when the steering gear of his tractor fails. PC Mason suspects sabotage, but Brown does not want any fuss. As a matter of fact he just wants the police to forget it ever happened. And with good reason too because Brown is not very popular with the other sheep farmers and most of them have it in for him. Old Mrs. Brooks has died and Aunt Peggy's solicitor Ronnie Smethers is the executor of her estate. Aunt Peggy offers her services to clear the house - at a reasonable charge, of course. Not surprisingly, she can't help picking out the good stuff and selling it herself. When she leaves David alone in the cottage, he hears strange noises and gets afraid they have upset the old lady's ghost. Gina has hired young, handsome Billy Garrett to help out at the Aidensfield Arms while Oscar Blaketon is away on a golfing trip to Scotland, and especially Dawn feels attracted to him. He takes her out a couple of times, but suddenly he turns moody and withdrawn and does not want to see her any more.

The Ashfordly police, and especially PC Mason, are asked to assist DI Turner from the serious crime squad investigating a series of very violent robberies in the area. One of DS Dawson's informants points the finger at Steve Dempsey. When Mason and Dawson check out Dempsey, they are spotted by Dawn, who is on a girls' night out with her friends. When she gets home, she does not hesitate to talk about seeing Mason and Dawson. Division has found out that Dawson had an affair with an unnamed police officer, and she has been put forcibly back in uniform. Mason does not want her to take the entire blame, and he turns himself in. Aunt Peggy is cleaning for the former bank manager Edward Walton - without charge for a change. When she discovers a broom cupboard full of strange things he gets very abrupt, gives her a valuable pen for her efforts, and sends her away. When Oscar Blaketon accuses her of stealing his pen she realizes that Walton has become a kleptomaniac since his wife was admitted to a nursing home and decides to help him.

Vic and Eileen Needham have a violent row, and she makes a complaint against him for destroying some of her family heirloom. She also files for divorce. And that is just the beginning. Particularly with Eileen's solicitor Sylvia Swinton on the war path. Wars have been more peaceful than that. Stan Bickle pays Aunt Peggy a visit. He brings along his daughter Josie. The two women do not get along very well. Especially not after Josie begins to make passes at David and threatens Aunt Peggys influence on him.

There has been three break-ins within a week already and the fourth item on the burglars' "shopping list" is the Aidensfield Arms. Nothing but money was taken, and the police are without a clue until Aunt Peggy and other old people receive an anonymous envelope with 20 pounds each. Money that comes from the break-ins. Furthermore Carol Cassidy saw a car in Aidensfield at the time of the break-in at the pub with a man and a woman in it. PC Mason readily admits that he was the man, but to Carol's great annoyance he does not say anything about who the woman was. Douglas Philpot asks Oscar Blaketon and Alf Ventress to look for his son Ian, whom he and his wife Mary have not heard from for three months. A colleague of his also saw him at a night club in Whitby, but that is all. The two sleuths have a feeling though that Mary Philpot knows more than she is willing to say with her husband present.

PC Younger arrests a tramp Ewart Martin, but when he puts him in the nick Martin immediately recognizes his old war buddy Sergeant Miller who is none too pleased to see him. Among Martin's things, Younger finds a business card from Leslie Rumbold, an insurance agent who was shot dead on his doorstep the same morning. Has the old tramp anything to do with the murder? Or is the perpetrator Ross Tillman, a farmer who has threatened Rumbold with his life? Another clue may be a photograph that PC Mason finds at Rumbold's office. Alf Ventress moves in at the Aidensfield Arms when his chimney goes through the roof and he needs a place to stay during repairs. Gina says he can stay for free and soon he is eating her and Oscar out of house and pub. And that is just for starters. No wonder Mrs. Ventress preferred to stay at her sister's instead. PC Wetherby has had his family staying for a couple of days, and when chances are he and his estranged wife may get back together again he asks Gina for advice. But Oscar Blaketon misunderstands and thinks Wetherby is making a pass at her again.

An unidentified man is found badly injured by the roadside near Aidensfield and PC Mason thinks he was assaulted. A complaint about a van blocking the way in Back Lane leads not only to the identity of the unknown man, but also to a load of condemned meat which has now disappeared. And soon they have the first case of salmonella poisoning. Aunt Peggy is asked to keep an eye on a mansion for three weeks. And being Aunt Peggy she cannot see why she should not make a little extra money on it herself and do some bed and breakfast in posh surroundings. Her first customer is a very surprised Alf Ventress. He had outstayed his welcome at the Aidensfield Arms - and one of the cells at the police station - and was asked to move out by Sergeant Nokes, who is filling in for Sergeant Miller. Alice Howarth asks Nurse Cassidy to look after her mother Edna who is so old it is not safe for her to be living alone anymore. But Carol is surprised to discover that the old lady is not so alone after all. Her son - Alice's brother - has returned to the area and visits her every night. Only he committed suicide twenty years ago. Dawn finds an old sewing machine and soon the only thing on her mind is sewing.

Safe breakers break in at Adams Brothers. One of them accidentally activates the alarm just as PC Mason passes on his motorbike. They manage to get away, but the next day their driver is found floating around dead in Whitby harbour. Is this the revenge of his accomplices for leaving them when the alarm went off or...? PC Mason also suspects it was an inside job because there was an exceptionally large amount of money in the safe. Meanwhile the rest of the gang stays comfortably at the Aidensfield Arms planning how to get another crack at the safe. It is Dawn's birthday and Gina organizes a surprise party for her. But Dawn is not the only one who gets surprised. Alf and PC Younger wonders why PC Wetherby disappears every day at lunch break and Oscar Blaketon bets them £5 that he can find out in a matter of hours. He gets a surprise too.

A mysterious man steals David's taxi (and his breakfast), but he does not get very far. Bernie recognizes the car and refuses to give him some petrol. The taxi robber is soon apprehended. He has obviously been in a fight because his face is bruised, and he claims he cannot remember who he is. While Nurse Cassidy takes care of his injuries, PC Mason is called out to assist Sergeant Miller. A dead woman has been found at the foot of a rock, and Miller agrees with PC Mason that the two cases are connected. Alf Ventress and Oscar Blaketon are planning a camping trip to France to see all the places they passed through during the war - on push bikes! They get a few tips from James Moncrieff, a fellow war veteran who is on holiday in Aidensfield.
