Braling comes back home late at night. His wife is already asleep. Another person enters the room. It is a robot, indistinguishable from the man. It becomes clear from the conversation between the two that the man, frustrated by his wife's passionate but stifling love, has bought the robot to double for him in various situations. He is determined to fulfil his life-long dream and spend a month's holiday on Tahiti all by himself. The robot has been furnished with ordinary human desires and emotions. It has fallen in love with Braling's wife and does not want to return to its box when the month is over. The wife wakes up, and believes that her husband was on the phone with someone. He denies everything and returns from the bedroom to the living room. The robot informs him that it intends to go to Tahiti and take the beloved woman with it. Then it attacks and strangles Braling. Back in the bedroom, it lovingly caresses the sleeping woman.
