The story presented here is almost certainly a work of fiction. During the robbery of a train station paymaster, one of 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.
What's actually novel about this story, something I haven't seen before in any Western, has to do with not one, but two women actually getting knocked out by outlaws! A henchman named Red (Don Kennedy) slugs Frankie, and later on, Doolin uses a horse collar to knock Sarah unconscious! Apparently outlaws in the Old West didn't make allowances for the fairer sex.
However the resolution of the story here is rather weak. Bill Doolin is captured and sent to prison, and in an escape attempt he's shot and killed. A rather unceremonious ending to a rather weak episode.
