A flawed attempt to map the mind of a brutal serial killer leads to a horrifying battle for survival in director Thomas Wright's visceral thriller. Despite vocal objections from Warden Blakely (Dennis Hopper), prison psychologist Diana Purlow (Dina Meyer) journeys deep inside the mind of serial killer Jesse Mowat (Pavan Grover) in a desperate attempt to reveal the source of his psychotic tendencies. Taken to the edge of insanity by a horrific discovery in the mind of her troubled patient, Dr. Purlow's worst fears begin to come true when Mowat survives his execution in the electric chair and embarks on a killing rampage.
