Tom and Wendy seem like the perfect couple, happy together and very much in love. But at night when Wendy sleeps, Tom has terrible memories about being stuck in a burning building with a crying baby. The nightmares, however, aren't real and neither is Tom. He's an android and the ""memories"" are bugs placed in his artificial intelligence by his creator, the late Joe Walker. Walker had originally created Tom to save humans from fires and other dangerous situations. However he anticipated that his colleague, Dr. Edward Normandy, might try to militarize the android and use him as a cyber-soldier-spy and planted the bugs as a way of forcing Normandy to upgrade Tom so the android could think for itself.
