Set in the Old West, the story is about train-robber Harker Fleet (George Peppard), who is sent to prison for assaulting a sheriff and his deputy while trying to escape a forced marriage, set up by his former partner, Timothy Xavier Nolan (John Vernon). Fleet serves his time, but gets out of prison early, for good behavior. Once he is released from prison, he travels to the town of Calador, intending to settle the score with Nolan for railroading him and stealing his woman, Katy (Diana Muldaur) .
