Montana Belle (1952)

In a fictionalized biography, Oklahoma outlaw Belle Starr meets the Dalton gang when rescued from lynching by Bob Dalton, who falls for her. So do gang member Mac and wealthy saloon owner Tom Bradfield, who's enlisted in a bankers' scheme to trap the Daltons. Dissension among the gang and Bradfield's ambivalence complicate the plot, as Belle demonstrates her prowess with shootin' irons, horses, and as a surprisingly racy saloon entertainer.
