Clint Walker (Cheyenne) is a soldier of fortune looking for payback in this rock-solid Western, the first live-action film produced by Hanna-Barbera. When soldier-turned-mercenary Jack Rutherford (Walker) returns home to his wife (Stefanie Powers) after spending years as a prisoner of war, he finds she's sold their ranch and run off with another man. Trailing her south of the border, he discovers she's living with Simon Fuegus (Pedro Armendariz Jr.), a Mexican revolutionary who's used the ranch money to buy ammunition and guns. So when Fuegus refuses to give him his share, Jack decides to kidnap the rebel and regain what is rightfully his. Alex Karras costars in this offbeat adventure from John Llewellyn Moxey, director of the cult favorites The City of the Dead and Genesis II.
