Nine people explore a cruise ship at sea in a manner that turns their whole lives upside down.
 
FUN FACT:  Paul Gallico was inspired to write his novel by a voyage he made on the Queen Mary. When he was having breakfast in the dining room, the liner was hit by a large wave, sending people and furniture crashing to the other side of the vessel. He was further inspired by a true incident which occurred aboard the Queen Mary during World War II. Packed with American troops bound for Europe, the ship was struck by a gargantuan freak wave in the North Atlantic. It was calculated that if the ship had rolled another five inches, she would have capsized like the Poseidon.
