Band leader Jack Conrad is impressed by prison inmate Ray Ferrera on saxophone. Conrad hires Ray to join his band and tour upon his release. Ray hooks up with Jean, a dancer in the show, and the two become a successful dance act. However, when an ex-inmate buddy of Ray's robs the tour bus, Ray is suspected of wrongdoing by Jack and the others in the group. After a gang of thugs hijacks the tour bus, Ray tries to use his street smarts to redeem his reputation.
