The Vengeance of Doctor Mabuse

Andros is a Frankenstein-like creature with scars indicating brain surgery and a highly disfigured face. He and Leslie work as a team for the evil criminal Dr. Mabuse. They are tasked with kidnapping a woman who is on the staff of the McDowell Institute for Laser Research. Mabuse hopes to obtain the plans that the institute has developed for a super-weapon that can send deadly laser beams via satellite. Leslie and Andros lie in wait for the woman to return from an evening date. Andros sneaks in through an open bedroom window and renders her unconscious. As he is taking her to their vehicle, neighbor Jennifer Hering watches the abduction from her house. Mabuse has his headquarters in an abandoned light house along the Pacific Coast of California. His assistant Hermann injects the kidnap victim with a hypnotic drug. She is then subjected to rays from an electronic apparatus that will coerce her divulge the answers to any questions. In response to queries about the plans, she indicates that two men will be dispatched with the plans from the institute in the morning around 6 A.M. The dose of the hypnotic was too strong, so she ceases responding to further questions. Andros takes her outside to toss her body into the ocean. She almost escapes, but gets caught at the last minute. The truck carrying the laser weapon plans leaves the institute at 6 A.M. as told to Mabuse. He sends Leslie and Andros to fetch them. They release a sleep-inducing gas over the highway. When the truck occupants fall asleep, they quickly substitute an identical document case for the one containing the weapon plans. Mabuse learns that the plans are encrypted. They are of no use unless he can find code key. Jenny, who witnessed the original abduction, comes in to speak with young Inspector Thomas. She is a cabaret dancer at the Red Garter. She does not have much additional information to help with their investigation. Mabuse is very anxious to get the code. He thinks he may be able to use Jenny to blackmail Dr Orloff, director of the project. He worries that they only have two days or the mob who hired them will kill them instead of paying them half a million dollars for the weapon plans. He has Leslie go to the Red Garter to pick her up. Leslie feigns being an agent interested in managing her. She gets Jenny loaded and then drives her to a construction site where Andros can render her unconscious. Thomas and his assistant Melou are on a stake out. They try to follow Leslie, but Melou's older model car breaks down. They lose them for the time being. But in the time it takes Andros to subdue Jenny, they catch up again. Leslie spots them tailing her and has Andros shoot at them. They back off. Mabuse has Hermann plant microphones in Orloff's office so that they can listen in on any conversations. This will help because Orloff will be visiting with a CIA agent and Professor Parkinson tonight. Maybe Orloff will talk about the code. Wanda, Thomas's fiancée and Orloff's niece, goes to see her uncle. He tells her that something important was stolen, that is, he caught on about the switch in the plan's document box. Mabuse says that they can catch him when he comes for the code in his safe. He then decides it would be better to just kill Orloff and bring his niece Wanda in to their headquarters. Leslie and Andros sneak into Orloff's house and strangle him. When Wanda comes out of her bedroom to check on noises she has heard, they grab her. Jenny is injected with a hypnotic serum and told to visit with Professor Parkinson to find out how much progress the CIA has made on the laser project case. Meanwhile, Jenny's partner Tom has gone to Thomas complaining that Jenny did not come home last night and did not show up for rehearsal at work. They head to the club for clues as to her whereabouts. Jenny charms Professor Parkinson. She manages to let him no that she is under Mabuse's control. He calls Washington DC to let them know about Mabuse's ploy. Leslie and Andros take Jenny back to her lock-up room. Andros is attracted to Jenny. This upsets Leslie and she slaps him with a rope. A fisherman shows up at Thomas's office and tells him that he witnessed a girl being taken under complaints into the old lighthouse. Andros and two other men head for the Institute to get the laser plans out of the safe. They kill the receptionist in the lobby and head up to Orloff's office. A security guard comes in and notices the front desk is vacant. He calls for assistance as plastic explosives are being packed around the safe's lock. Institute guards shoot it out with the burglars. Two guards and two of the three thieves go down. Andros escapes and flees the scene. He stops a car, punches out the driver, and absconds with the vehicle. At Mabuse's headquarters, Hermann tells Andros that he was careless. Andros strangles him. Wanda has escaped from her room and is looking to help Jenny when Andros catches her. Leslie is upset to see Andros with Wanda. Then, Mabuse shows up, too. Mabuse puts Wanda under the interrogation ray. This raises Andros's ire. He breaks the ray machine, chokes Leslie, and throws Mabuse into the ray machine electronics. Mabuse is instantly electrocuted. Andros heads outside toward the ocean carrying Wanda just as Melou and Tom show up. Melou shoots Andros, freeing Wanda. Tom runs inside and finds Jenny safe. Thomas and Wanda embrace. This whole nightmare is finally over.
