The Fat Spy

On a small island near Florida, a dozen teenagers combine singing and dancing on the beach with a search for buried treasure. Wellington, the island's wealthy owner, is none too happy about that, so he dispatches his daughter, Junior, to get rid of them. She's happy to go because her sweetie, Irving, is the island's only resident. Junior sends Irving to spy on the kids to find out what they know. Is the Fountain of Youth real, and, if so, who will get to it first?
