Don Carlos, a dashing Mexican adventurer, and his guitar-strumming friends, Pedro and Philipe, ride into the Lazy Y Ranch on the Texas border and become enamored of the beautiful sisters Dolores and Raquella.

Gus Aldrich offers a reward for the capture of rustlers who have been stealing his cattle, and the trio embark on their mission; but Don Carlos dallies over a pretty girl at an inn and runs into trouble with her bullfighting brother, Antonio.

At the hacienda of Don Roberto, he encounters Lolita, who tries to persuade him to kill Gonzales, her fiancée, whom she is being forced to marry; but he escapes and, locating the stolen cattle, drives them back to the ranch.

The Bad Man, Antonio, and Gonzales arrive bent on vengeance.  Don Carlos accepts the reward and drives the adversaries into a food cooler; after evading the clutches of the quarreling señoritas, Don Carlos kidnaps the innkeeper's daughter and rides into Mexico.
