By pure chance, Jessie and his four jazz musicians are hired to play at the cabaret theatre “Trocadero”. Unfortunately, she knows nothing about music and it doesn’t help that all four musicians are in love with her. Jessie doesn’t reciprocate their feelings, because she has a thing for Martin. Unfortunately, Martin believes that Jessie stole his car … and so, right before the premiere at the cabaret, she ends up in jail.
