Juggernaut

A desperate scientist will resort to anything, including murder, to continue his experiments. In need of money, the sadistic Dr. Satorius (Boris Karloff) accepts an offer from a millionaire's wife, Lady Von Clifford (Mona Goya), to murder her ailing husband, Sir Charles (Morton Selten). He injects the victim with a deadly poison, condemning him to a slow death. The millionaire alters his will to favor his son Roger (Arthur Margetson) before perishing, instantly making him the target of his stepmother's murderous intentions. (Verleiher-Text)
