Jim Wainwright's barn burns down and although the fire was started deliberately Wainwright claims it was an accident and not worth any police attention. The next day the headlights of George Allsop's Land Rover are smashed and he too says it is not a police matter. PC Ventress and PC Bradley think otherwise because the Wainwrights and the Allsops have been in a feud with each other for many years although things have been quiet between them for a long time. But they may be starting up again. Vernon Scripps thinks Aidensfield and other villages need a cinema. He gets a projector from a closed-down sex club and plans to drive around and show pictures at the village halls. Joyce Jowett is against the idea and wants to have final approval of the films.

Oscar Blaketon has organized for PC Crane to take a group of troubled youths on a hike across the moors for one day. At the last moment they get an additional participant Carl Laxton, who is the cousin of Geoff, one of the other participants on the trip. But Laxton may have an ulterior motive to go on the trip. Of course Steve Crane's mother chooses that moment to pay her son another and more permanent visit by the looks of it. She has even got a job as assistant librarian under the supervision of Joyce Jowett. Needless to say they do not hit it off. Mr. Shahrishi is the leader of a sect which has just lost the place they were staying in, and while he enjoys the comfort of the Aidensfield Arms his followers must make do with a clearing in the forest, and he does not get on with anybody. He is on the lookout for at new place to stay, which gives Vernon Scripps an idea. At first Lord Ashfordly turns him down, but then changes his mind. Not a wise move on his part.

With no village bobby in Aidensfield Tommy Unsworth and his motor biking friends seizes the opportunity to make a lot of trouble in the village. Even Aunt Peggy is upset that the bikers are trespassing on Lord Ashfordly's land upsetting the natural order of things by frightening the game away and leaving her traps empty. But when it will take a while to get at permanent replacement Miller organizes a stop gap. Thus PC Joe Mason moves to Aidensfield on a temporary basis while he awaits his transfer to the Met. Mason is very resourceful and a bit of a maverick, and his senior officers were more than happy to get rid of him. The villagers are not too crazy about him either. But Unsworth is not the only source of trouble around. A professional gang from Manchester is targeting country houses in the area stealing paintings, antiques and jewelery.
