Ageing swingers Donald and Jacqueline Stewart return to the Hotel Solanas in Benidorm for another holiday. New guests this year are middle-aged virgin Geoffrey, who calls himself the Oracle because of his quiz general knowledge, with his mother - or P.A. as he terms her - gay couple Gavin and Troy, young marrieds Kate and Martin who have been going through a sticky patch, and the Garvey family. Lazy Mick and his long-suffering wife Janice have a lippy teen-aged daughter Chantelle and inquisitive little son, Michael. Janice's sun-burnt, chain-smoking mother Madge, who rides around on a mobility scooter has paid for the holiday for them all. Janey York is the jolly if half-hearted holiday rep and then there is Mateo, a sexy young waiter with an eye for the ladies. . . Kate in particular.

It's karaoke night at the hotel bar and the Oracle and his mother perform a duet, but that's not the reason Chantelle Garvey faints. When her mother finally opens up the pink coat Chantelle has refused to shed despite the Spanish heat, it is revealed that she is very pregnant.

Kelly, an English girl who works at the hotel, tells her friends Donald and Jacqueline that she is engaged to Mateo. This, however, is not enough to stop Mateo from making a pass at Kate and having sex with her, though she later admits that she was too drunk to remember anything about it. Janice, meanwhile, reconciles herself to becoming a grandmother.

Due to a misunderstanding Donald and Jacqueline assume that Madge is up for group sex with them and she gets a shock when she answers an invitation to go to their room. They have a lot of apologizing to do. So does Troy, who gets drunk and ends up having sex with Mateo, which Gavin observes. Janice believes that her husband is planning to get off with Susie, a single woman who is following him around.

The Oracle is outraged that a quiz veteran like himself is beaten , more by luck than judgment, by the Garveys in the pub quiz and demands a recount though he doesn't get one. Kate is annoyed that Madge , in whom she has confided about her difficulty in conceiving, has broken her trust whilst Donald reassures Gavin that Troy still loves him.

Having stayed within the complex for all of the holiday because everything is inclusive, Mick is horrified when his family drag him off to the beach and he is forced to pay the extortionate prices. Worse is to befall him, however, when the girl Janice thought was after him turns out to be a D.S.S inspector who ends up prosecuting him for claiming he is unable to work but going on holiday. The Oracle also decides that he will never go on holiday with his mum again, but Martin is pleased at his wife's fling with Mateo, feeling that it has spiced up their lives.

Everyone is back at the Solanas, in Kate and Martin's case not exactly by choice. They had booked into a small hotel in the romantic Old Town but were double-booked and end up in the old complex. The Garveys are being paid for by Madge's boyfriend, Mel, who owns several tanning salons in Manchester. Mick does not really like him but tolerates him because of the free holiday.

Kate starts to feel broody and she and Martin spend the evening baby-sitting Chantelle's child Coolio. Everyone else goes to the hotel bar's karaoke where, after a very high-pitched rendition of 'Lonely Girl', Mel proposes to Madge.

Janice tries to dissuade Madge, unsuccessfully, from getting married. The Oracle organizes an arm-wrestling contest, where the last two sitting are Martin and Mateo. For Martin it's personal and, cheered on by the Brits, he humiliates Mateo and becomes Kate's hero again.

Everybody heads off to a bullfight, except for Chantelle and the Oracle. Somewhat apprehensively she asks him for a date and he accepts. The bullfight is meant to be free to enter but Mel has to buy a food mixer from Janey, the travel rep, before the party are allowed into the corrida. It is a farce; there is no bull, just a large dog with a hat with horns on chasing Mateo around the ring.

Kelly, Mateo's ex-girlfriend comes to the Solanas with her mother, Sylvia, who like Madge, rides an electronic scooter. Madge is convinced that Sylvia is out to steal Mel from her and squirts her with sun tan lotion before pushing her and the scooter into the swimming-pool. Martin is suspicious that Kate is trying to get back with Mateo and breaks into the bedroom he believes they are using. Instead he finds swingers Donald and Jacqueline terrorizing Mateo by inserting a cucumber in one of his orifices.

Angry and upset that Mick has forgotten their wedding anniversary, Janice goes off for a walk on her own and stops off at a bar. It is owned by Jack, an English lad in his early twenties, along with his sister, both orphans. Jack tells Janice that she is beautiful and that he is in love with her but she panics and hurries back to the complex.

Kate disappears with her luggage, and Martin, after an initial assumption that maybe she had gone to the shops tracks her down. She has good news for them. Dorothy, the mother of Gavin, half of the gay couple, comes to visit. Gavin is annoyed by Donald and Jacqueline's constant comments that he and his mother look the same age. Jack also comes to the complex in search of Janice, declaring his love for her, though she gets rid of him. Chantelle and the Oracle's date is ruined when he drinks too much Dutch courage and passes out.

On the eve of their wedding, Madge and Mel take a stroll along a romantic, moonlit beach, only to discover that it is a 'dogging' beach where people go for public, casual sex, and they are importuned by a man up for a threesome. (Needless to say Donald and Jacqueline are there as well.) The wedding day dawns and Janice has a pep-talk with Madge - she is the only one of Madge's five daughters still speaking to her. Assured that her mother is making the right decision, she takes her place at the beach ceremony, but the marriage is not finalized because the Oracle hang-glides out of the sky, falling onto Mel. Mick hits him and gets arrested whilst the groom is carted off to hospital.

Following Madge and Mel's wedding, Janice and Madge hitch a ride to the hospital with a stranger who turns out to be the wanted criminal Enrique "The Rat" Lopez. When the pair are held hostage, it's up to the other guests to rescue them.

For their part in capturing Enrique "The Rat" Lopez, the Brits return for their reward, a free holiday. Martin has separated from Kate and brings along the younger, vulgar Brandy, though both insist they are just friends. Mel is opening a shop renting mobility scooters ("You don't have to be a cripple to enjoy your holiday") employing lazy young Paco and his poolside reunion with Madge is passion personified. Mel gets Mick to publicise the opening by having him ride a twenty foot bike whilst wearing tinfoil, which cooks him in the heat. Everyone turns up for the grand opening - largely because of the free champagne. However, due to faulty lighting the shop catches fire.

Noreen, the Oracle's mum ,assumes he is gay when he tells her he is not interested in currently dating women and she seeks advice from Gavin and Troy. Whilst most of the other guests are on a day trip to a water park, the Oracle goes to an internet cafe and meets, online, a woman called Lesley, though, unbeknown to him, Lesley is actually a transvestite. At the water park Mick antagonizes everyone by arguing with Madge and Mel and Martin ends up in the nude when Brandy steals his clothes whilst he is swimming.Back at the bar Mick makes up with Janice when he says it with flowers but Martin sends Brandy packing for humiliating him and she ends up kissing Paco. The biggest humiliation is reserved for the Oracle, however, when his mother 'outs' him from the karaoke stage and performs 'Y.M.C.A.' with the Stewarts and Gavin and Troy dressed as the Village People, causing him to flee in horror.

Having finally convinced his mother that he is not gay, Geoff the Oracle goes to meet Lesley, his internet chat date. However he is shocked to find that Lesley is a transvestite and makes his escape halfway through their dinner, leaving Lesley to cop off with the maitre d'. Mel takes the sea-sick Garveys on a trip to Peacock Island, where he hopes to buy land for development, only to be told that it is a protected nature reserve. Brandy beds Mateo, stealing his pass-key in the process,but returns to Martin, saying that she only has eyes for him.

Gavin gets into an argument over a burger with a hefty woman with a young Indian husband in tow. Madge is shocked to see it is Valma, one of her estranged daughters, who has come to Benidorm by coincidence. Valma is a wealthy landlady but, despite Janice's best efforts to bring a reconciliation, Madge is convinced that she has followed them out to get Mel's money. Someone who is after Mel's money is Gary, a con man, who poses as a property developer. His accomplice is Brandy, who is also his girlfriend, and they fleece the tourists, using the pass-key Brandy stole from Mateo, to access their rooms. Whilst Madge, high on Ecstasy tablets which she mistook for pills, is performing 'Up, Up and Away' at the karaoke night, the two crooks make their getaway.

The Brits count the cost of the burglary. Kate flies out to support Martin, sending Madge packing when she suggests that Martin was an accomplice, and giving him hope of a reconciliation. His mother Diana also arrives, and seems to know the area - and particularly Mateo - better than she should. The Oracle is almost arrested for wasting police time when he lies about trying to foil a whole gang of burglars but gets another date with Chantelle, and Troy confesses to Gavin that he has a son, aged twenty-one. Madge and Mel are entertaining everyone on the trampoline at the new cabaret club when news arrive that the burglars have been caught.

Martin's hopes of marital reconciliation are ended when Kate tells him she has a new boyfriend and leaves without him. However, he does get to meet someone else and there are happy endings too for the Oracle and Chantelle who plan to move in together on return to Manchester,and the gays as Troy introduces Gavin to his son. Wink, an obnoxious friend of Donald, who annoys everybody with his practical jokes, has no such luck as, taking things a joke too far, he literally dies laughing at the karaoke. Madge and Mel have decided to relocate to Benidorm, where Mel is to buy the cabaret club and, as the others return to England, they serenade them all with an oddly affecting version of 'Spanish Eyes'.

The surprise is on the Garveys when their surprise visit to Madge reveals that she has sold the Palace and her villa - to Cilla Black - and left no forwarding address. They book in to the Solana,where the Stewarts are also staying.With Troy at his dying father's bedside Gavin has returned with work-mate Kenneth,who never stops eating. Cross-dressing Les is the new poolside barman and his gormless young son Liam is smitten with pretty tourist Natalie,to the scorn of her sarcastic friend Sam. When Madge is finally located she reveals that Mel left her with huge debts,forcing her to sell up and move into a trailer park from which she has just been evicted as she owes rent. Janice decides she should stay at the Solana with them and the family and staff close ranks to see off Scary Mary,the park owner,when she comes to collect Madge's arrears.

Noreen arrives in Benidorm with her bossy daughter Pauline who alienates the Garveys with her manner but ends up inside a rubber ring with Mick at a water park,causing Janice to suspect the worst. Natalie agrees to a date with Liam to spite Sam who comes too and falls off a table while dancing. Janey is impressed by Lesley's initiative,which annoys Mateo, who falsely claims that children are scared by his transvestism.This backfires on him when Janey suggests that he should also drag up to make it seem more natural.Madge's uncharitable response to the Stewarts' whip-round to ease her financial woes also comes back to bite her.

Gavin is puzzled as to how the supposedly penniless Kenneth is raking it in after taking strange men to his room until it turns out that he is giving them hair-cuts. Mateo reluctantly begins his water aerobics class,which ends with Donald being taken to hospital. Janey is all for sacking the Spaniard but Lesley comes to his defence,reminding him that he now owes him. The Garveys learn that a gangster calling himself Mr. Pink has bought Mel's debts and go to meet him at a deserted theme park. He challenges Madge to a Go-Kart race,which she wins,thereby cancelling the debts as well as gaining her an extra three thousand euros,thanks to a side bet.

The resort is hit by a rain storm which floods the hotel. Whilst Les takes control Janice is thrown by the appearance of Johnny Neptune,whose marriage proposal she rejected years earlier. Reformed alcoholic Pauline is so bored she gets drunk and makes a show of herself when she wins the bingo and insults everybody before collapsing on Janey's dog. Donald drops a bombshell by announcing that he has only three months to live and tries out 'The Drugs Don't Work' at the karaoke as the song he would like played at his funeral.

Gavin learns that Troy's father has died so,to cheer him up, Kenneth takes him out for the day but,by design,ends up at a gay nudist beach where he gets chatted up by a bare hunk. Gavin is not pleased and sacks him. Madge has the chance to take over a bar - the site of Mel's former disability shop. She prays for a sign and gets one in the form of one of Mel's old thongs and agrees to go into business. Mateo accompanies Les on a double date to repay him for getting him his job back. Unfortunately Mateo has to drag up and gets arrested for importuning.Bananarama arrive for the 1980s evening and get mistaken for a tribute band as there are only two of them. Jacqueline,however,successfully makes up the trio but Liam is less successful in his persistent pursuit of Natalie.

After Donald's clothes and a suicide note are found on a beach Gavin and Kenneth help Jacqueline bid him farewell. The British consul however suspects an insurance fraud. Due to a misunderstanding at a gladiatorial theme park Janice finds herself in the arena where she defeats all-comers. Troy arrives in Benidorm,a wealthy man after his father left him several houses and four hundred thousand pounds. Pauline celebrates a successful divorce,Liam declares his appreciation of his father and Madge opens her bar,publicly thanking the Garveys for their support whilst Mateo is exposed - literally - as a cheat with a wife and children. Most of the Brits head home,except Jacqueline,who has an appointment in Morocco.

A busload of guests including Noreen,Gavin minus Troy and Sam with her raucous friend Trudy arrive at the Solana,unlike their luggage which got lost on the way. There are several changes - Madge has lost her bar,Kenneth has opened his own salon with local Carmen as his assistant and Liam is the complex's clumsy odd job man. Most significantly Janey has gone,replaced by snooty Joyce Temple-Savage,who aims to make the Solana more up-market - or at least efficient,having arrived incognito and been shocked by what she sees. This leads to open conflict with Madge and the near demise of Jacqueline and Donald,who has returned from the dead and a jail sentence for faking his death to claim the insurance whilst Sam,having broken her leg last year,has yet another mishap.

Kenneth starts to regret employing non-English speaking Carmen and offering free treatment at the salon as first prize in the dance contest Joyce is organizing,to be judged by her old flame,professional dancer Cyril Babcock. Janice is puzzled when young Jack,her former stalker,reappears and claims not to recognize her,involving her in a fight with Trudy. However come the contest he sweeps her off her feet confessing it was all a ruse to get close to her. Fortunately Mick comes to her rescue whilst Gavin and Carmen win the competition,releasing Kenneth from giving the prize.

Mick is not pleased when his gormless younger brother Pete,who owes him money,arrives for his stag party with cantankerous father Stan in tow. Nonetheless a fancy dress bar crawl ensues but all ends in anti-climax when Stan admits that there is no wedding and Pete is just taking a break from being his father's carer.After Joyce insists there should be life guard cover at the pool Trudy plans to get the kiss of life from Mateo but ends up being revived by Les dressed as Pamela Anderson whilst Kenneth's misreading of a text from Troy almost leads to his splitting him up from Gavin.

Hearing that a gang is abducting people to sell their organs,the Garveys are alarmed when Michael sees Madge getting into a car with a swarthy young man. Giving chase they learn that he is Mohammed,a Moroccan whose father did business with Mel and who is returning some of her late husband's belongings to Madge. Joyce aims to impress Victor St James,editor of the 'Costa Class' magazine,mistakenly believing that his loutish behaviour is a front to catch her out. After Mateo has burnt the paella and Trudy nutted Victor for thinking she was a prostitute Joyce is fearful of a negative review. However salvation comes from a most unlikely quarter. Donald and Jacqueline meanwhile set out to meet some swingers but,due to a misunderstanding,Gavin and Noreen unwittingly beat them to it.

After their night with the swingers,which Noreen enjoyed without understanding,she and Gavin get locked out on his balcony whilst Madge shocks her family by announcing her forthcoming marriage to Mohammed as a tax dodge to regain money owed to Mel by his father. The British Olympic Synchronised Swimming team arrive at the Solana,led by frosty Hazel McCafferty. Joyce delegates Liam to show the girls around but they trick him into taking them onto an 18 to 30 booze cruise. Whilst Trudy and Michael fail in their efforts to join the cruise as being too old or too young,come evening the girls are too smashed to give their gala demonstration. Fortunately Lesley saves the situation with an impromptu pool party and Joyce gets her own back on the snide Hazel.

As Madge prepares for her wedding to Mohammed Mick and Michael discover that he is no rich business man's son but a penniless actor out to marry Madge for her supposed fortune. The Garveys follow him to a medieval tournament recreation where the would-be groom gets his 'joust' deserts. Trudy meanwhile tries to play a trick on Sam by convincing her that she had sex with Liam but Sam and a borrowed pregnancy testing kit have the last laugh. Concerned that the Solana's bad press is due to a spy in the resort leaking all the disasters that have befallen it Joyce asks Donald and Jacqueline to shadow the staff to expose the culprit. Their result leads to a face from the past.

When elegant Barbara Simmonds arrives Joyce is sure she is the hotel inspector who will give the Solana its fourth star so it is not a good idea for Joyce and Kenneth,angry because his salon has been closed for non-payment of rent,to start brawling in front of her. To compensate Joyce offers Mrs Simmonds free beauty treatment but of course she has been misinformed though fortunately she is able to bribe the real inspector. The Stewarts seek the help of the consul to see off Donald's heavy ex-cell mates but Mick has to admit failure when he tells Madge that all her - uninsured - tanning shops burned down ,though Michael still has faith in him.
