Roy Rogers is a secret investigator for an insurance company trying to locate a payroll stolen five years ago. He obtains a job singing on the showboat Yellow Rose of Texas from Betty Weston (Dale Evans), whose father was convicted and imprisoned for the robbery. When Sam Weston (Harry Shannon) breaks jail to clear himself of the framed charge, Rogers helps get the evidence that traps the real culprit.
The musical sequences are pleasant and well staged, enhanced by some good singing and dancing, and there is enough action to satisfy those who like excitement in their westerns.
Rogers acts and sings in his usually accomplished style, and Evans makes a decorative addition to the film with her fine singing and dancing, while Bob Nolan and the Sons of the Pioneers do well with their numbers. Rest of the cast is competent.
