A nationalist musician, Hélio, plans to stage a samba show at a luxury hotel nightclub. The owner, Ademar, influenced by his daughter Marisa, is only interested in big jazz acts. Hélio, aided by Bebeto and Dorothéia, presents a fake Dorothy Bridge and a Sunday Júnior, parodies of Eartha Kitty and Sammy Davis Junior. While being covered by these fake artists, Hélio searches for a singer for a repertoire based on Carmen Miranda.
