Vaughn is Bob Ford, the man who killed Jesse James. Along with McNally, Vaughn wants to leave the James gang after the film's opening holdup. McNally wants to give up being an outlaw to marry Vaughn's sister, Castle. Since both are still wanted by the law, Castle makes a deal with the
governor, who will pardon both of them if Jesse is brought in dead or alive. Vaughn is the one who finds Jesse and shoots him in the back, which is close to historical fact. McNally is then able to marry Castle and live in peace. This was the first big-screen role for TV star Vaughn, master of the
mildly neurotic characterization.
