A 1986 demonologist, Elise Rainier, helps a family whose son Josh is being haunted by the spirit of an old woman.

Specs and Tucker find a video of the 1986 investigation and discover an adult Josh standing behind young Josh.
The group goes to an abandoned hospital and discovers the story of a patient named Parker Crane who was a serial killer known as "The Bride in Black". Josh's body begins to deteriorate and he is revealed to be possessed by Parker. In the spirit realm, Josh and the others find Parker's house where they witness Parker's mother abusing him and forcing him to kill his victims. Elise destroys Michelle's spirit, freeing Josh. Some time later, Specs and Tucker arrive at another house with a girl in a coma, and Elise's spirit passes between them to the girl's room, where she is confronted by an unseen figure.
