A capsized ocean liner, a kidnapped heiress, a terrorist leader and the U.S. Marines who takes them all on - get ready for intense action deep in the water when Lt. Colonel Alan Decker (Costas Mandylor) finds himself in the middle of an international terrorist plot to kidnap the daughter of an oil tycoon. Terrorist leader Lazo orchestrates a nuclear test in nearby waters in an attempt to disable all airborne and surface surveillance equipment. But without warning, the blast creates a massive tidal wave that capsizes the ship, and threatens the lives of everyone on board. Now, Colonel Decker and Captain Josephson (James Coburn) are the only hope for survival and must make their way through the sinking ship to reach the ocean's surface before it's too late.
