Newlywed Ruth Stanton Bowman boards a luxury ocean liner with her husband, John, expecting to begin a romantic honeymoon. Soon after departure, however, John mysteriously disappears. Even more disturbing, no one aboard remembers seeing him, his name is missing from the passenger list, and the cabin they shared appears to have never been occupied by him. As the crew begins to question Ruth’s sanity, ship doctor Paul Manning becomes one of the few people willing to believe her and help uncover the truth.
