In the Wild West, vicious but bumbling bandit brothers Emmett (Ernest Borgnine), Frank (Jack Elam) and Rufus Clemens (Strother Martin) botch a heist, and in anger they rape local woman Hannie Caulder (Raquel Welch), murder her spouse and destroy her home. Set on retribution, Hannie seeks out bounty hunter Thomas Luther Price (Robert Culp), who helps her learn to shoot -- a skill she that she'll need as she attempts to track down and take out the merciless Clemens brothers.
