An illegal radio station is transmitting from a ship just off the coast outside Whitby. When nurse Bolton starts seeing a young man called Danny the villagers are hearing wedding bells already. But a bit too soon it seems as he turns out to be her brother. Danny helps PC Rowan get a position as a DJ at the illegal radio station. Joe Norton is out of prison after serving a sentence for arson. He wants to turn a new leaf and has sent in an application to join the paratroopers. While he waits for an answer he helps out in PC Rowan's garden and hangs out with old friends. They fix him with a new drug that really sends him flying. Joseph and Greengrass think that George is charging too much for his drinks and decide they can do better end cheaper themselves.

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.
