Two musicians whose dance band is going nowhere happen across a roadhouse in the sticks, where a pack of fun-loving youngsters are dancing to a new and different beat -- the kids call it rock 'n' roll! The band, Bill Haley and his Comets, leaves the two musicians mighty impressed, and they agree to manage Haley and his crew. They soon meet disc jockey Alan Freed, who immediately secures Haley and the boys a nightclub stand in the Big Apple, where the Comets become the hottest ticket in town. Haley and Co. perform most of their best-known tunes here, including "See You Later, Alligator", "Razzle Dazzle", "Rudy's Rock" and (of course) the title tune.
