 The raunchy group from Billingson University hits the high seas for a cruise on a ship down the Mexican cost where the action revolves during one weekend during a school play involving a stolen diamond called the Pharohs Heart, stolen by the university anthropologist Professor Cavendish who wants to sell on the black market. But Cavendish is murdered by an unknown killer before he can do so and the diamond goes missing. Rejoining the group is Booker McFee who is trying to forget about his girlfriend Rachel who is also on the ship. Meanwhile, geekish Newmar wants to go all the way with his latest girlfriend Violet who wants to take things slow. Stoners Pete and Wang are trying to score some good dope and instead hook up with a mischievous kleptomaniac monkey named Choo Choo, while Pete is competing with Rachel for a college grant for a research project. Dim-witted gossip queens Lynn and Marla are also stirring up more trouble while Pete s friend Cliff, now a fugitive, works as the ship s pirate bartender while Gerri is around as well as stage director Foosball. Secondary characters include the University Dean Dryer and the ship s captain who s wife is sought after by every guy on board.
