Alice Faye stars as a singer trapped in a lousy stage act called the Trio from Rio (with Joe Durant and Frank Mitchell). They are in a failing stage show starring a fading actress (Bebe Daniels) who acts like she's still queen of Hollywood.
When Daniels heads back to Hollywood, the trio follows, hoping to break into movies. In that grand theatrical tradition, they all land in the same movie with Daniels. But Daniels is temperamental and refuses to sing "hot" so she is replaced by Faye.
In a subplot, Daniels brings her kid sister out west, but the sister has designs of Daniels' boy friend. Only after the kid sister has an accident do we learn the truth.
The entire cast is lively. Alice Faye sings great and dances a little. Bebe Daniels (age 34) steals the film as the fading star; she's just terrific. Mitchell and Durant have a hilarious restaurant scene as dueling Tarzans. Co-stars include Ray Walker, Rosina Lawrence, Andrew Tombes, Hattie McDaniel, Luis Alberni, Hal K. Dawson, and Grace Hayle as the laundry manager with special talents.
