Pushed out of a moving vehicle, a 10-year-old boy (Barret Oliver) is found by an elderly couple and brought to an orphanage. All he can remember is his name, Daryl. Sent to foster parents Joyce (Mary Beth Hurt) and Andy Richardson (Michael McKean), Daryl is the perfect son. When his picture appears in the local newspaper, however, his "real" parents (Kathyrn Walker and Josef Sommer) come to claim him. Returned to a top-secret military base, Daryl is revealed to be a robot and is ordered to be destroyed. Escaping, Daryl steals a fighter jet, ejects just before the plane's blown up, and returns home to his foster parents.
