Frankie Avalon and Annette Funicello star in Muscle Beach Party as fun-loving surfer Frankie and beach bunny Dee Dee. The pair is ready to surf some waves, soak up some sun and dance the day away. But when their favorite beach spot is overrun by a group of body builders and their obnoxious trainer, Jack Fanny (Don Rickles), it seems unlikely that fun in the sun is on the menu. And with the newly arrived Julie (Luciana Paluzzi), a spoiled, rich Contessa that has her sights set on having Frankie all for herself, it's a battle on the beach for Frankie, Dee Dee and the gang. William Asher (TV's I Love Lucy, Bewitched) directs.
