A young ballet student (Margaret O'Brien) becomes upset when the dancer (Cyd Charisse) she idolizes loses the lead in a production of "Swan Lake" to a visiting prima ballerina (Karin Booth).

Now, O'Brien must cope with devastating guilt while Charisse goes on to be a star. Danny Thomas (in his film debut) co-stars in this absorbing drama. 101 min.
