Rusty Wells and his band are just about ready to leave Chicago for their annual spring break trip to Fort Lauderdale. That is, until Big Frank extends their stay at his club. Big Frank’s daughter decides to go to Lauderdale with her friends for spring break, so he gets Rusty and his band to look after her and to make sure she stays out of trouble. While he attempts that, Rusty has to contend with a good-time girl, Deena, who has no patience for guys who stand her up or keep her waiting.
Elvis stars as struggling pop singer Rusty Wells, whose musical combo works for a tough Chicago nightclub owner known as Big Frank.
Big Frank’s big weakness is his only daughter Valerie, who insists on spending her Easter vacation in sunny, sinful Ft. Lauderdale.
Frank sends Rusty and his friends to Florida to keep an eye on Valerie without her knowing about it.
Rusty attempts to pursue a few college coeds of his own, but he is constantly interrupted by the need to rescue Valerie from various Ft. Lauderdale loverboys. Naturally, Valerie, played by Shelley Fabares in her first Elvis Presley musical, falls in love with the smooth-talking Rusty.
