In the beautiful North Yorkshire countryside of the 1960s, Constable Nick's roles are as varied as the eccentric villagers. He handles every encounter with his characteristic humor, humanity, and professionalism.

His investigations include the case of a clever pony who keeps escaping, a woman running through town naked, and a pack of Canadian timber wolves hanging out in a bus shelter.

He soon gets to know all the characters on his beat, from his superior officer Sergeant Blaketon to Claude Jeremiah Greengrass, whose lurcher Alfred lands him with a summons for "allowing a dog to worry livestock on agricultural land." The ever-resourceful Claude Jeremiah offers the defence that Alfred's victim, a budgie, cannot be described as livestock!
