Roy Martin aka Roy Morgan is a burglar and former war-time Radio & Electronics Engineer who listens in to radio police calls, allowing him to stay one step ahead of the cops.

All-American singing cowboy Jimmy Wakely went below the border in this musical Western from the assembly line at Monogram, performing such ditties as Adios Mariquita Linda, Rose of the Rancho, the inevitable La Cucaracha, and his own title tune. As always, Jimmy Wakely plays himself, this time heading for Don Roberto Lopez's (Julian Rivero) ranch to track down a missing gold shipment.
