A mysterious crook by the name of "The Poet" is robbing Wells Fargo stages and creating havoc in the Old West. The sheriff is having no luck discovering the desperado's identity; when he comes across James Wylie (Dennis Morgan), a gambler who is running from the law in Carson City, he blackmails him into going undercover and tracking the outlaw down. Wylie takes the next coach out, joined by two tantalizing women, Ann (Jane Wyman) and Emily (Janis Paige). Emily is just a saloon singer (which affords her the chance to croon "I'm So in Love" and "Going Back to Old Cheyenne"), but it turns out that Ann is more unusual -- she's the wife of The Poet. The two team up to track him down (encountering The Sundance Kid and his gang along the way) -- and discover that they make a pretty good team. A popular TV series of the same name was loosely based upon the movie; starring Clint Walker, it ran for 7 years starting in 1955.
