In this supenseful and provocative high-seas drama, the captain of a luxury liner is suddenly faced with life or death decisions when his ship sinks, leaving himself and a few survivors floating at sea in an overcrowded lifeboat that does not contain enough food, water and medical supplies to support them all. The captain, Alec Holmes (Tyrone Power) is a decent fellow, and initially intends to save everyone. But it soon becomes clear to one of the ship's men, Frank Kelly (Lloyd Nolan) that this is impossible. As Kelly sacrifices himself by leaping overboard and into the sea, he shouts out a warning to Holmes that it will be necessary to rid the boat of its ill passengers if the rest are to survive, as not enough food and water exists to provide for everyone. Defying the requests of his sweetheart, Nurse Julie White (director Mai Zetterling), and his buddy and fellow officer, Will McKinley (Stephen Boyd), Holmes disposes of the sick individuals on board. He initially gains the support of the rest of the passengers, but when a rescue ship finally turns up, their support turns to contempt and hostility. In Great Britain the story is titled Seven Waves Away.
