An underwater luxury hotel on a gorgeous tropical island is set for an extravagant opening weekend with the world watching. The only thing standing in the way of a first-rate experience for the jet-setting VIPs is an unscrupulous businessman and 60 feet of prehistoric shark. As the underwater complex is besieged by a marauding behemoth, newly minted marine biologist Coco Keahi must face off against the ancient predator as it rises from the deep with a vengeance. Meanwhile, a human monster has decided he would be better off if Coco were one of the creature's victims.
