Jockey Club investigator David Cleveland journeys to Canada to apprehend a notorious horse doper and while there is coaxed by his supervisor to help rich horse breeder Harry Teller. Teller has been trying to find Chrysallis, his $6 million dollar stud bay stallion, mistakenly kidnapped by hijackers and presumed dead. Although Cleveland initially resists the case, an attempt on Teller’s life convinces him the horse is still alive. Cleveland is intrigued further by Teller’s hard-drinking, lonely and curvaceous second wife as well as his nubile blond daughter, both of whom are attracted to him. He teams with an overweight insurance investigator to track down the animal as clues take them to dude ranch in the Canadian Rockies.
