As the luxury liner Poseidon slices through the waters of an ocean storm, a radical terrorist group is preparing to send a bloody message to Western politicians. Shortly after the 2,500 passengers and crew have celebrated New Year, a huge blast rips through the hull, sending freezing waters rushing through the lower decks and capsizing the mammoth vessel.

Trapped in the ballroom with the water level rising fast, a small group of passengers led by Homeland Security Officer Mike Rogo (Adam Baldwin, Full Metal Jacket) and the ship’s priest (Rutger Hauer, Blade Runner) must make a break for the surface, braving the twisted inferno of the wreckage or risk being lost to the ocean floor forever.
