In the not-so-distant future, David, a robot with actual human feelings, especially a never-ending love for his "mother," Monica, is adopted as a substitute for her real son, who, afflicted with an incurable disease, remains in "cryo-stasis." David lives happily with Monica and her husband, but when the couple's real son returns home after being cured, David's life changes dramatically. Directed by Steven Spielberg and based on the short story "Super-Toys Last All Summer Long" by Brian Aldiss.
