Frank Rivers had served four years in the penitentiary for the murder of his father in the commission of a stagecoach robbery. There had been a witness that could not be found at the time of the trial, but who's testimony four years later was sufficient for Rivers to receive a full pardon. But for Rivers the matter is scarcely ended. He wants to find the real culprits behind the crime. His search leads him to Ute Springs where he immediately comes to the notice of Sheriff Jim Echols, who believes that Rivers committed the crime and that he bribed his way into being granted a pardon. When Rivers witnessess the murder of his prime suspect, he has a touch decision to make. Flee and be blamed or stay and be blamed.
