Tough, lusty Catlow (Yul Brynner) is fast on the draw and even faster when it comes to making a dollar. He's also a wanted man. The Mexican Army is after him. So are his hellcat girlfriend (Daliah Lavi), an Indian war party, a vengeful killer (Leonard Nimoy) and several hotheaded cowpokes from Catlow's outlaw gang. Then there's Catlow's best friend, Marshal Ben Cowan (Richard Crenna), who wants the pleasure of putting Catlow behind bars all to himself.
