Former child actor Johnny Downs acts his first adult lead in this nonsensical but charming little musical which benefits greatly from the appearance of Eddy Duchin and his band. To keep troublesome socialite Johnny Marvin (Downs) out of mischief, Coronado Hotel manager Carlton (Jameson Thomas) persuades Duchin to hire the lad as a band member. Johnny falls in love with singer June Wray (Betty Burgess), but she mistakenly believes he is interested in her sister Violet (Alice White), newly married to sailor Chuck Hornbostel (Jack Haley). Marvin Sr. (Berton Churchill) and June's vaudevillian father Oscar (Leon Errol), meanwhile, conspire to keep their offspring apart by exaggerating their differences, but after a jaunt into Mexico -- during which the young hero impersonates a doctor in order to spring Chuck and his pal Pinky Falls (Andy Devine) from the local jail -- Johnny and June are reunited with the blessings of their fathers. Accompanied by Eddy Duchin and His Orchestra, Betty Burgess, Johnny Downs, Jack Haley, and Leon Errol perform "All's Well," "Coronado by the Sea," "Doing the Coronado," "You Took My Breath Away," and "Down on the Isle of Oomph," all by Richard Whiting and Sam Coslow.
