Summer, 1983. A showman has sunk every dollar he has into a resort on a Florida island the Seminole have warned about for three hundred years. A British documentary director arrives with four beautiful young performers to shoot the commercial that will save him. A county marine biologist arrives to find out what is wrong with the lagoon. Nobody on that island will say what is in the water. By Sunday, every one of them will wish they had.
