Child psychologist Malcom Crowe is one night visited by an ex-patient named Vincent, angry, enraged. He wounds Crowe, then kills himself. A few months later, Crowe is visited by a 9-year old boy named Cole. He sees dead people who do not know they are dead. Because of this, he is called a freak in school. Crowe, at first thinks he is seeing things, but after spending a lot of time with Cole (much to his wife's dismay), he discovers Cole may be seeing dead people after all.
