Plot
A stranger, calling himself Jeff Young, imposes on rancher Lucy Lee for a meal and a night's rest, then saves her from being robbed. Jeff helps deliver her cattle to town, where he encounters Kit Banion running her saloon, The Maverick Queen.

Kit is secretly in cahoots with the notorious Hole in the Wall Gang, led by Butch Cassidy and Sundance, and a jealous Sundance is angered when Jeff beats him at poker and attracts romantic interest from Kit, who offers Jeff a job as a faro dealer. He reveals he is actually Jeff Younger, a relative of the Younger Gang outlaws, and wants to help Kit and her associates with their illegal holdups.

Lucy is held captive by Sundance after a train robbery, and Jeff ends up killing him to save her. Holding off the other outlaws while their cabin is on fire, Jeff is helped by Kit, who is shot and dies in his arms. The posse arrives, whereupon Jeff confesses that he is actually a Pinkerton detective, working undercover to catch the thieves.
