The 00 Cyborgs are spending a day of relaxation by painting the body of their ship, the Dolphin. Jet Link has just finished painting his illustration of a shark face and a pretty woman on the nose of the Dolphin (in a similar manner to how pilots would paint the bodies of their war planes in World War I and World War II), but then he gets angry at Geronimo, Jr. when he paints white lines over it. Then Great Britain gets into a scuffle with Chang Changku when the latter painted a Chinese dragon over his psychedelic-looking picture, only to end up accidentally knocking a bucket of yellow paint on Pyunma's head. While an angry Pyunma chases the two cyborgs for it, Dr. Gilmore arrives, worried that his friend Professor Kozumi hasn't come back yet. Joe Shimamura asks him about Kozumi's whereabouts, only to have Albert Heinreich tell him that he has left to do some errands...when Francoise Arnoul's enhanced senses detect something far away. Dr. Gilmore, Great Britain, Albert, Joe, and Francoise drive along the cliff side road and discover Kozumi's abandoned car along the corner, along with his hat and fresh footprints and tire tracks, revealing that he had been kidnapped. Dr. Gilmore sends Great Britain, Albert and Joe to investigate the tire tracks while he and Francoise look for clues. The guys' tire track search eventually leads to a dead end at the edge of a cliff, but they also discover a large mansion in the forest just a distance away. Upon traveling there, Great Britain senses something odd about the mansion. He is scared away when he sees a shadowy figure behind the door, but when a beautiful woman living inside the mansion appears, Great Britain instantly falls in love with her. While the woman serves them tea, Joe and Albert ask her about the whereabouts of Professor Kozumi, when they look at the mirrors behind and notice something odd. When asked why she lives alone, the woman explains that her husband has left for unknown reasons and is currently waiting for him to return. Great Britain is appalled and pledges to be the woman's trusted confidant and friend so he can ease her loneliness, but is interrupted when Joe and Albert abruptly decide to leave. Unknown to the trio, the woman's shadow morphs into the same shadowy figure Great Britain saw earlier. That same night, Joe, Albert, and Great Britain return to the mansion, this time to investigate it. Great Britain is reluctant to investigate the woman they met earlier, but is forced to go along with them when he is left alone outside in the dark. Inside, the mansion is made even creepier with all sorts of sinister-looking memorabilia inside, and Great Britain is scared when the chime of a grandfather clock echoes through the hall. While the three investigate and come across all sorts of scary things, the woman they met is seen seated in another undisclosed room, playing a chess game that appears to be manipulating the inner surroundings of her house. In one part, Great Britain discovers a room that has its doors shut in on him, only to open normally when Joe and Albert arrive and the entire room disappears after they leave. When the trio notices that they have been going around in circles, they are attacked by the floor rug and manage to evade it, but Great Britain was flattened in the process. Great Britain justifies the floor rug coming alive as part of the woman's "security system", much to Joe and Albert's disbelief. The second time the floor rug attacks, the trio escape it by going through a doorway leading off its path, only to slide down the stairway when it flattens itself. They end up in a room of spikes and are nearly killed when Great Britain saves them by transforming his arms into octopus legs and hanging onto a ledge. Then they are sucked up an air duct and end up a room where they are nearly crushed by the walls and ceiling closing in on them, when Great Britain turned himself into a pole and accidentally created a hole into the floor, leading to him and his friends falling into another room with lots of pictures. After investigating the pictures and several unopened letters, they learn that the woman's husband had never returned from one of the World Wars, and that she could be possibly dead herself. Suddenly the woman's voice appears and reveals itself as Cyborg 0012, which consists of the whole mansion being part of a large trap used for kidnapping people, including Professor Kozumi. Great Britain, Joe, and Albert try to escape but end up trapped in the "stomach" of the house, where dissolving acid is being poured in to kill them. Using their quick thinking, they manage to barely escape by shooting a hole in the wall with their guns and end up in the drawing room. Cyborg 0012 reveals that she has caught them and tries to kill the trio with an electric stimulator beam. Joe saves his friends by going into acceleration mode and shoots at a mirror, destroying it and revealing a machine with 0012's real body encased inside.
