Girl Happy (1988)

As his daughter, Valerie (Shelley Fabares), sets off on a spring break trip to Florida, thuggish businessman Big Frank (Harold J. Stone) insists that singer Rusty Wells (Elvis Presley) shadow her. Valerie warms to Rusty, but when she realizes that he's been paid to keep her out of trouble, she rebels, taking up with Italian womanizer Romano (Fabrizio Mioni). As her wild ways land her in jail, Rusty must deal with her father's wrath, Romano's threats and his own complex feelings for Valerie.
