Westward, Hoe!.

When a straight-laced New Englander flees to the Wild West to avoid being sent to an asylum, she feels threatened by chauvinistic cowboys and a territorial saloon girl, until she is protected by the dashing and silent outlaw, El Hombre. When she accidentally exposes that El Hombre is the bombshell saloon girl in drag, both women have to venture farther west to escape the law and reestablish themselves.
