60's sex symbol Raquel Welch stars as the gun-slinging, vengeful Hannie Caulder. Whilst fleeing the scene of a botched bank robbery, the Clements brothers (Ernest Borgnine, Jack Elam & Strother Martin) come across an isolated homestead. Whilst trying to steal new horses, the trigger-happy youngest brother murders Caulder, the landowner. This leaves his wife Hannie (Welch) unable to fend off the three Clements alone, and they rape her, steal her horses and burn her home to the ground. Hannie then teams up with Thomas Price (Robert Culp), a ruthless bounty hunter and ask him to teach her how to kill. He eventually agrees and they set off in pursuit of the outlaws.
