Frontiersman Vern Haskell wanders the West obsessed with finding the men responsible for murdering his fiancée. His quest leads him to Chuck-a-Luck - the film's original title - a combination horse ranch and criminal hideout overseen by saloon chanteuse Altar Keane. Posing as an escaped criminal, Haskell falls in with murderous gunslinger Frenchy Fairmont and slowly but surely becomes indistinguishable from those he is hunting.
