The Poseidon Adventure Collection

A passenger ship, on her way to the scrap yard is pushed to her limits by the new owners to save on the dismantling fees. A tidal wave hits her, flipping her over so that all the internal rooms are upside down. A priest takes a mixed band of survivors on a journey through the bowels of the ship in an attempt to survive.

After "The Poseidon Adventure" (1972), in which the ship got flipped over by a tidal wave, the ship drifts bottom-up in the sea. While there are passengers still on-board waiting to be rescued, two rivaling salvage parties enter the ship in search of money, gold, and a small amount of plutonium.
