Don Ameche plays a dual role, starring as Baron Duarte, a wealthy Brazilian industrialist, and entertainer Larry Martin, the young Rio de Janeiro performer who looks just like the magnate. Fortuitously, the highlight of the entertainer’s act is uncanny imitation of the industrialist, which impresses the latter’s associates. When Baron Duarte must leave Brazil on urgent business, Larry Martin is enlisted to help stave off the advances of the industrialist’s powerful enemies. The scene is now set for ensuing hilarity.
Naturally, all’s well that ends well in this charming musical comedy.
