A group of young friends set out for the deep sea fishing trip of a lifetime aboard a million-dollar dreamboat. Suddenly, an electrical fire rocks the boat, destroying their electrical system and engine, leaving them stranded with no communications in the deep Atlantic. The party becomes adrift with no way to contact help. As the days pass, food and water run short and the crew becomes desperate. Finally one of them spots a passing oyster boat and it appears that they are saved. But this boat has no intentions of saving anyone and is occupied with a group of backwoods watermen intent on terrorising them.
