Best friends Judy (Jane Powell) and Carol (Elizabeth Taylor) compete for the affections of an older man (Robert Stack) during their high school dance. As Carol tries to rekindle Judy's relationship with Carol's bumbling brother, Oogie (Scotty Beckett), Judy suspects that her father (Wallace Beery) is having an affair with a beautiful dance instructor (Carmen Miranda). The two girls team up to expose Judy's father -- who is only taking innocent dance lessons.
