The future has arrived at the Ashfordly police station in the form of the new sergeant George Miller and a state-of-the-art Ford Zephyr police car. He also has plans to close down the police house in Aidensfield and move PC Walker to Ashfordly permanently. Apart from that Sergeant Miller is very old-fashioned and extremely narrow-minded. His first case in charge of the Ashfordly police is a series of wage snatches. After yet another snatch PC Bellamy and the Zephyr's regular driver PC Yates give chase to two suspects in a Mini Cooper, but they are shaken off when the robbers go where the big police car cannot follow them, and only PC Walker on his motorcycle is able to keep up the pursuit, but crashes when the robbers block the road. The villagers of Aidensfield are not taking the possible loss of their police house lightly of course and organize a protest.

A couple walking their dog on the beach discovers a dead man by the water's edge. The only thing they can find out about him is that he died of a fall from a cliff. PC Walker is contacted by his old friend Jackie Pointer. Her brother Tony is in jail and he has picked up some information on a robbery being planned and is willing to share this information for an early release. Walker contacts Sergeant Miller, who will have nothing to do with the matter. Walker decides to see Tony anyway and maybe get some more information. Bernie Scripps is having one of those days where nothing goes right. As a matter of fact he has had a lot of those lately and Rosie is afraid he is seriously ill. Speaking of Rosie she has a date and asks Gina for makeup advice. She looks really hot when she is dressed up as a girl.

PC Bellamy takes over one of Alf Ventress' old contacts, Vic Smalley. From him he learns about Ray Craven, who is flush with money and it is not through taking sheep to market, which is his official business. But Bellamy does not exactly make the top of Sergeant Miller's charts when the police make a raid on one of Craven's lorries and find only sheep. When Gina tidies up in her guest Derek Ford's room she discovers that he works for the Inland Revenue. He is "on tour" in the area and Vernon Scripps is next on his list. In fact Scripps owes so much in back tax that he will never be able to pay it and he decides to do something drastic. Too late for him Oscar Blaketon discovers that Ford is a fraud with no connection at all to the Inland Revenue.

Sergeant Miller is "off to learn the patch" as he calls it when he spots a speeding car and give chase, but the driver, David's Aunt Peggy, easily manage to lose him, ruining his day completely. It will not be the last time she does that and their relation will soon be just like the one between Oscar Blaketon and good old Claude Jeremiah Greengrass. Rob Walker has been dating the nurse Clare Owen since she took care of him after he crashed on his motorcycle. They are both invited to a party celebrating the arrival of a new doctor at the hospital, Gavin Kennedy, who coincidentally also Clare's former lover. During the party another of Clare's colleagues does the high wire under the influence of drugs and alcohol and is seriously injured when he falls to the ground although Walker tries to stop him.
