David Banner(Bill Bixby) while trying to fix a car he purchased(for a change!) is assisted by a young girl named Jolene Collins(played by Robin Dearden) who turns out to be a runaway child prodigy who is being used as a research subject for the Kirkland Institute which is in hot pursuit of her, though Jolene only wants to meet the mother who gave her up, and enlists David's help to take her to her L.A. home, while trying to evade the police and change the heart of her reluctant mother. Heartfelt if a bit melodramatic episode with Dearden giving a fine performance, and amusing sequence of her exposing Psychic Surgery as a fraud while they work picking grapes with migrant workers.
