During the robbery of a train station paymaster, one of Bill Doolin's (Leo Gordon) henchmen is fatally shot, and giving the man up for dead, he writes a letter to the man's wife. Sarah Brinkley (Joan Shawlee) arrives in Ingalls, Oklahoma to collect her husband's share of the robbery money, but in the meantime, Railroad Detective Frankie Adams (Mary Castle) impersonates the wife searching for her 'missing' husband. Bill Doolin is captured and sent to prison, and makes an escape attempt.
