Raquel Welch is Hannie Caulder in this western saga of revenge and retribution. Fleeing the scene of a botched bank robbery, the Clements brothers come across an isolated homestead. In an attempt to steal fresh horses, the gumhappy youngest brother, who blew the bank job, bungles again, this time murdering Caulder, the landowner. His wife, Hannie (Welch), is unable to fend off the three Clements alone. They rape her, steal the horses and bum her home to the ground. Bent on revenge, Hannie teams up with Thomas Price (Culp), a ruthless bounty hunter. She implores him to teach her how to kill. Reluctantly he agrees, and together they set off in pursuit of the outlaws.
