Devil and the Deep

Charles Sturm (Laughton) is a naval commander whose jealousy and abuse makes life miserable for his wife Diana (Bankhead). His suspicions fall on his own subordinate, Lieutenant Jaeckel (Grant). Although his suspicions are baseless, Sturm has Jaeckel transferred. After Charles falls into another fit of paranoid rage and strikes Diana, she wanders off into the streets during a festival and soon encounters another officer, who turns out to be Jaeckel's replacement, Lieutenant Sempter (Cooper). Learning of their affair, which this time is real not imagined, Charles plots a terrible revenge.
