Harry Markle is being trailed by bounty hunter Hanson who fakes a campsite luring Markle into trying to ambush him which fails. Hanson takes the captured Markle into Laramie and turns him over to acting deputy sheriff Jess Harper for the night. Markle recognizes Jess although Jess has no idea who he is. Jess owes Markle his life when Markle cut him from a hangman's noose five years earlier. Markle is now accused of robbing the American Mail Company and killing the night watchman and he claims he's as innocent as Jess was on that long ago day. Jess repays the debt at the expense of his reputation, by letting Markle go then goes to Daggett to prove Markle's claim. He takes a job with the mail company and starts nosing around. Someone at the company office is a blackmailer and someone a murderer as Jess gets closer to the truth. The closer he gets the more dangerous it becomes. Proving Markle innocent may cost Jess his life.
