Alan and Dennis open a new restaurant in Ashfordly, but they are victims of vandalism and somebody also hands out false free-meal coupons on their behalf. The primary suspect is Sid Wainwright, who was interested in buying the place too. Gina gets a visit by her old friend Debbie, but Aunt Mary believes that Debbie will only get Gina into trouble, but instead it is Debbie who lands in trouble. Professor Booth is searching for the burial site of Wulfstan the Wealthy, a mighty Anglo-Saxon chieftain and Greengrass is convinced that the burial site is on the lands of Terence Young, whom he has already relieved of some "surplus" rainbow trout, and tries to find it first and sell his finds to the professor.

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.
