Irwin Allen's second water-logged disaster film picks up where The Poseidon Adventure left off; Salvagers Michael Caine, Karl Malden and Sally Field enter the Poseidon to take what they can, unaware that evil salvager Telly Savalas and his henchmen lie in wait. When an explosion rocks the ship, the enemies find themselves trapped inside in a battle for survival both against nature and themselves. The good guys pick up some survivors along the way, including Peter Boyle as a stereotypically hot-headed Italian, Mark Harmon as the All-American boy next door, and Slim Pickens as the ship's wine steward in what may be one of the most poorly-written parts of all time. Field looks good in the water, and Caine is charming despite a lack of material, but the merits end there.
