Irene Vail decides to divorce her husband, the rich ship owner Bruce Vail. However, Bruce learns that he can prevent the divorce if he can provide evidence that she has been involved with another man. He pays his driver Michael to visit Irene's hotel room in
Paris and pretend to be her lover so that a private detective can catch them in a compromising position. However, a man overhears Irene's startled cry upon finding Michael in her room, and a struggle ensues when the man defends Irene, leaving Michael on the floor, unconscious. When Bruce and the detective burst into the room, the man threatens them with a gun, demands Irene's jewelry and takes Irene hostage. Once they are away, the intruder, Paul Dumond, returns Irene's jewelry and invites her to dine with him at the Château Bleu restaurant, where he works as a waiter. They dance and Irene falls in love with him. In the morning, Irene returns to find Vail and the police in her room, as Michael is dead. Vail leads her to believe that Paul is responsible for the murder and blackmails her into coming back to the United States with him in exchange for Paul's freedom. Distraught that he is unable to find Irene, Paul learns that Irene has reunited with her husband and left for the U.S. Sensing something is wrong, he embarks for the U.S. to find her, accompanied by Cesare, his good friend and head chef of Château Bleu. In Manhattan, Paul and Cesare rehabilitate a restaurant, hoping that it will attract Irene. The reunion takes place at last, but Paul learns that Michael is dead and that a man has been arrested in Paris for the murder. Unwilling to let an innocent man pay for what he thinks is his crime, Paul embarks for Paris, and Irene joins him. They travel on the liner
Princess Irene, which is owned by Vail and named after her. Vail learns that they are on the ship. In a rage, he orders the captain to travel at full speed, despite the danger of collision with an
iceberg, claiming a desire to break
the record for fastest crossing. Vail actually hopes that the ship will sink, killing Paul and Irene. The ship does strike an iceberg, and premature news reports state that the ship has sunk with tremendous loss of life. Consumed by guilt, Vail commits
suicide and confesses to killing Michael in a note. However, the ship's bulkhead doors contain the water and prevent the ship from sinking. Paul, Irene and the other passengers rejoice when they hear that they are to be rescued. ==Cast==
