THE FAT SPY

A mostly deserted island, which is believed to be the home to the fountain of youth, lies off the coast of Florida. The island gets some visitors in the form of a teenage rock band, The Wild Ones, and their gang of swimsuit-clad young people, including Frankie (Jordan Christopher) and Nanette (Lauree Berger), and their sidekick Dodo (Johnny Tillotson). The gang heads 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 wealthy owner, George Wellington (Brian Donlevy), recruits his daughter, Junior (a then-pregnant Jayne Mansfield), to remove the teenagers from the island. Junior is eager to see her love interest (and the island's only resident), rotund toupee-wearing botanist Irving (Jack E. Leonard). 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. Meanwhile, Irving's twin brother Herman (also Jack E. Leonard, without a toupee), Wellington's trusted employee, plots with his love interest, the scheming Camille Salamander (Phyllis Diller), to find the fountain of youth first.
