In this tense tale of psychological terror, Dr. Malcolm Crowe (Bruce Willis) is a child psychologist whose new patient has a problem far outside his usual area of expertise. Cole Sear (Haley Joel Osment) is six-years-old and claims to see the spirits of dead people all around him. It seems that Cole has psychic powers and can channel the ghosts of those who were troubled. Cole doesn't understand his powers, and he has little control over them; he's constantly terrified by what he sees, and Dr. Crowe is the only one with whom he feels he can share this secret. However, as the doctor digs deeper into Cole's strange powers, it leads to strange and unexpected consequences for both of them. M. Night Shyamalan, who wrote and directed the film, has a small role as Dr. Hill.
