Synopsis:
It's New Year's Eve and festivities have begun aboard the luxury cruise ship Poseidon, at sea in the North Atlantic. One of the finest vessels of its kind, Poseidon stands more than 20 stories tall, boasts 800 staterooms and 13 passenger decks.

Tonight, many of the ship's guests have gathered to greet the new year in style in the magnificent Main Ballroom. They raise champagne glasses as Captain Bradford delivers a holiday toast. Meanwhile, on the bridge, the Chief Officer senses that something is wrong. Scanning the horizon, he sees it ¡V a rogue wave; a wall of water over 150 feet high, bearing down on them. He tries to steer the ship away from maximum impact but it's too late.

The wave strikes with colossal force, pitching the ship heavily to port before rolling it completely upside down. Passengers and crew are thrown into free fall, crushed by debris or dragged into the sea as water bursts in through shattered windows. Supports collapse, broken gas lines ignite flash fires and lights fail, leaving vast sections of the ship in darkness and chaos.

In its aftermath, a few hundred survivors are left to huddle in the still-intact Main Ballroom, now resting below the waterline. They should stay together, the captain maintains, and wait here for rescue. One man, Dylan Johns, prefers to test the odds alone. Ignoring orders, he prepares to exit the Ballroom and find his own way to safety. But he is joined by nine-year-old Conor and his mother Maggie, Robert Ramsey who is looking for his daughter Jennifer and her fiancˆm Christian, a shy stowaway, a suicidal man, and a young waiter with knowledge of the ship's layout. Determined to fight their way to the surface, they must forge a path together through layers of wreckage as the ship continues to sink. Bonds form quickly in this journey of vertical climbs, dead ends and sheer drops. And trust proves vital.
