Blaketon and Nick go after a criminal who thinks he's untouchable when a dim-witted local lad called David Stockwell reports an illegal badger digging ring in the woods and his mother is involved in a hit-and-run accident. Meanwhile, Greengrass' past cons against local shareholders serves as the source of aggravation when he and George buy shares in a racehorse. Elsewhere, Ventress is revising for his Sergeant's exam, and uses it as an excuse to get out of police work.
