This lively musical comedy pays tribute to the birth of rock & roll in the late 1950s and the instrumental role played by disc jockey Alan Freed who helped bring the new sound into vogue. Much of the story centers on the daring deejay's attempts to put on the very first live rock & roll stage show at the Paramount Theatre in Brooklyn.
To do this he must overcome the protests of concerned and angry parents, conservatives, and local police. Several performers of the era appear in the film including Chuck Berry, and Jerry Lee Lewis.
