Mostly inspired by the 1969 book and 1972 film, The Poseidon Adventure, the game is set in 1921, and the players must escape the sinking ship Lady Crithania, which gets hit by a gigantic wave and is capsized.

The game features four playable characters, each with a different story:

– Capris Wis……显示全部her, an architect. This young man takes his younger sister Amy to the Lady Crithania. However, Amy's sickness becomes a severe hindrance to him.
– Redwin Gardner, a counselor traveling with a family consisting of an unnamed mother, her children Stella and Harry Adams. Plus, Jack Hamilton, a nephew.
– Jeffrey Howell, a senior doctor that travels along with his wife Adela.
– Luke Haines, a crewman of the Lady Crithania. He suspects that the sea conditions are too much for the Lady Crithania to handle, much to the opposition of his superiors.
