It's a killer... a Diller... a blast of laffs!
A mostly-deserted island, which is believed to be the home to the fountain of youth, is off the coast of Florida. The island gets some visitors in the form of a teenage boy band, "the Wild Ones", and their gang of swimsuit-clad young people, who head there in a crowded powerboat ostensibly for a scavenger hunt. However, they spend about half their screen time crooning to each other, or dancing on the beach. The island's owner, Wellington recruits his blonde daughter, Junior , to remove the teenagers from the island. Junior is eager to see her love interest, rotund toupee-wearing botanist Irving . However, Irving is more interested in flowers and his bicycle than in the amorous Junior. Wellington asks Irving to spy on the teenagers, which he does by donning a sweatshirt that reads "Fink University", and "getting their trust" by joining them in dancing the Turtle.
