An aging steamship cruises toward a South Seas Island for a photo shoot, on board, a bevy of beautiful fashion models. The crewmen, the medical officer Dr. Rawson and the modeling agency's photographer plot a mutiny their plan to sail the ship to a remote island where they'll take advantage of their good fortune and use these voluptuous young women for their kinky sexual pleasure. Once the captain and his officers are set adrift in a lifeboat, the ship sails toward the aptly named, Lust Lagoon. Meanwhile, below deck, the girls are suspended in chains and stripped naked, delighting the men with their beauty, as they are prepared for a special initiation. Later in the ship's ballroom, Dr. Rawson begins the night's festivities, setting the girls free to hide about the ship, becoming prey for the lusty crew who will chase after them. Once captured, they're taken to the cabins for a nightlong siege of sex and punishment, followed by days of carnal amusement. The bondage, whipping, electric prods and torture continue as the girls are savagely tormented while being primed for sex. Though some resist their captors, many learn that the wanton behavior demanded of them brings pleasure beyond their wildest imaginings. It would seem that a spell, cast by pagan gods, has descended over the entire cast of players in this unreal fantasy come true. But all it not perfect in paradise! When the lovely Josie and her friends escape from the prison hold, they kidnap Dr. Rawson and take him to the island where they bind him in a cave and give him a rough taste of his own medicine. While they may enjoy their scheme for the moment, but they should be advised that a rough punishment awaits when they are found. In time, the ship is discovered by a spy satellite. Will this mean rescue for the imprisoned girls? Or are they destined to sail into the hands of more ruthless captors, who will take them to the slave market where they will be sold as slaves?
