A man has created a machine. Now the machine wants to create a man.
Susan Harris (Julie Christie) is alone in the house when, suddenly, doors lock, windows slam shut and the phone stops working. Susan is trapped by an intruder…but this is no ordinary thug. Instead, the intruder is a computer named Proteus, an artificial brain that has learned to reason. And to terrorize. Packed with suspense, surprise and special effects, Demon Seed follows Susan’s desperate attempts to outmaneuver and outthink her captor. Then Susan learns what Proteus wants: its own child, conceived in her womb and destined for domination.
