A luxury liner has capsized in the middle of the ocean, and it's up to the few remaining survivors to navigate through the treacherous, upside-down maze of terror and make their way to safety in the made-for-television remake of the 1972 disaster film. A terrorist has boarded the luxury liner Poseidon during a lavish New Year's Eve celebration, and when the blast of his bomb causes the immense ship to capsize, the struggle to make it out alive turns into a waterlogged nightmare as the ship slowly continues to take in water. But sinking isn't the only thing the survivors have to worry about, because within their midst the diabolical terrorist is waiting for just the right moment to finish the job he started when he planted the bomb.
