Plot
Nightclub singer Rusty Wells (Presley) and his band have just closed their engagement at the club where they work in Chicago and are about ready to leave for their annual spring break trip to Fort Lauderdale, Florida—that is, until the club's owner, Big Frank (Harold Stone), extends their stay at his club, foiling the band's plans for some sun and fun in Florida.
At the same time, Big Frank's daughter, college student Valerie (Shelley Fabares) also takes her spring break in Lauderdale with her friends, which worries her father to no end. So at the suggestion of Rusty (who sees this situation as an opportunity for him and the guys to make Lauderdale after all), Big Frank hires Rusty and his band to make the trip to Lauderdale to look after Valerie to make sure she stays out of trouble. But the task isn't easy because Rusty and the guys struggle to keep sex-crazed Italian exchange student Romano (Fabrizio Mioni) away from Valerie, while at the same time Rusty has to keep explaining the situation to his date, a good-time girl named Deena (Mary Ann Mobley), who has no patience for guys who stand her up or keep her waiting.
Rusty's watch over Valerie eventually leads to the two of them falling in love (after Rusty walks Valerie to her motel room, serenading her with "Puppet on a String"). However, after Big Frank reveals to Valerie that he is paying Rusty to be her chaperone, Valerie becomes angry and devastated to the point of going to a local nightclub, getting drunk, and starting a riot, landing everyone there in jail.
