Young Jamie Halsted is camping out with he parents. He is very sad because his dog Sam is missing, and when a man dies of rabies Sam gets under suspicion because Jamie's father is a former army major, who has been stationed abroad, and Blaketon organizes a major search for the animal in order to stop the disease from spreading. There's a new police car in town, and PCs Rowan and Ventress take it out for a spin. It has been some time though since the last time Alf Ventress was behind the wheel.

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.

Gordon Radford and Lord Ashfordly are not the best of friends. As a matter of fact Radford is not on friendly terms with anybody. He is Master of Ashfordly Hunt and when somebody vandalizes his study during the hunt suspects are plenty in number, but Radford suspects Lord Ashfordly and takes it out on him in a very physical manner. Aunt Peggy uses David's aniseed balls to lure the hunting party across her garden in order to claim a huge compensation. But she does not fool Oscar Blaketon. PC Mason is on the lookout for a car and Bernie has just the one for him. Low mileage and only one careful owner - a nun none the less, but Mason is more interested in a sports car owned by the late fighter pilot Ginger Wells.
