In late 1890s Wyoming, Butch Cassidy is the affable, clever, talkative leader of the outlaw Hole in the Wall Gang. His closest companion is the laconic dead-shot "Sundance Kid". As the west rapidly becomes civilized, the law finally catches up to Butch, Sundance and their gang. Chased doggedly by a special posse, the two decide to make their way to South America in hopes of evading their pursuers once and for all.
