The Sundance Kid is the frontier's fastest gun. His sidekick, Butch Cassidy, is always dreaming up new ways to get rich fast. If only they could blow open a baggage car without also blowing up the money-filled safe inside... Or remember that Sundance can't swim before they escape a posse by leaping off a cliff into rushing rapids... Times are changing in the west and life is getting tougher. So Butch and Sundance pack their guns, don new duds, and, with Sundance's girlfriend, head down to Bolivia. Never mind that they don't speak Spanish, they'll manage somehow.
