Dr. Jonas Carson (Alan Thicke) creates an Android (robot) that looks just like a human teenage boy, and he "adopts" him as his son and as an older brother to Becky (Robyn Lively), who names him Chip. After the Carsons move to a new town, Chip (Jay Underwood) is enrolled in high school alongside Becky. Dr. Carson also goes to the high school, having filled a vacancy as a science teacher, which allows him close range to see how Chip interacts with others.
