In flashback, Andre, Helene, and their son Philippe Charles Herbert are a happy family. Andre has been working on a matter transporter device called the disintegratorintegrator. He initially tests it only on small inanimate objects, but he eventually proceeds to living creatures, including the familys pet cat which fails to reintegrate, but can be heard meowing somewhere and a guinea pig. After he is satisfied that these tests are succeeding, he builds a mansized pair of chambers. One day, Helene, worried since Andre has not come up from the basement lab for a couple of days, goes down to find Andre with a black cloth over his head and a strange deformity on his left hand. Communicating with typed notes only, Andre tells Helene that he tried to transport himself but that a fly was caught in the chamber with him, which resulted in the mixing of their atoms. Now, he has the head and left arm of a fly and the fly has his miniature head and left arm, though he keeps his mind.Andre needs Helene to capture the fly so he can reverse the process. Although she expends great effort in her search, she cannot find it and Andres will begins to fade as the flys instincts take over his brain. Time is running out, and while Andre can still think like a human, he smashes the equipment, burns his notes, and leads Helene to the factory. When they arrive, he sets the hydraulic press and motions for Helene to push the button. She activates the press twice once to crush his head and once to crush his left arm. ........
