U.S. Navy Lieutenant George Blenton becomes drunk at an official reception, and his fiancee, Jane Ravenslee, the captain's daughter, breaks their engagement. After war is declared, George, entrusted with a secret code book to deliver to an English admiral, drinks and loses the book which German spies recover. During a private court-martial he is offered a pistol for suicide. After drinking again, he fires a shot, but still lives. Put ashore on the island of Tafofu "to rot," George, hating the U.S., moves in with Lehua, a half-white who tries to wean him from drink. Jane, still in love, attempts to find George, but her ship is torpedoed and captured by a German submarine. After the sub arrives at Tafofu to sink George's ship, the U.S.S. Victory , Lehua unsuccessfully tries to warn them. George, who has befriended the German captain, sees the Victory 's flag, and signals danger. The Victory sinks the sub, and George, while fighting the captain, is shot. After Jane finds his body, he is honored posthumously on the victory.—Pamela Short
