What actually happens
A childhood home with a red door in the basement
The story starts in 1953 in Five Keys, New Mexico, where young Elise Rainier shares a house with her brother Christian and their parents, Audrey and Gerald. A spirit in the children's bedroom scares both of them, and Christian drops the whistle Audrey gave him for calling her. Gerald doesn't believe Elise's story, so he beats her and locks her in the basement. There Elise finds a red door and opens it. That lets out a demonic spirit called Keyface, who kills Audrey. The rest of the movie follows Elise as she tries to deal with what she started that night, and with a father who handled the whole thing very badly.

Worst timing for a house call
Fifty-seven years later, Elise makes her living investigating hauntings alongside Specs and Tucker. Three years have passed since the Quinn Brenner case when a man named Ted Garza calls about paranormal activity at his house. Elise realizes it is the house she grew up in and goes to help. She finds Christian's lost whistle, but it vanishes again after a female spirit appears. Elise tells her colleagues that she saw this spirit once before, as a teenager, and that she later ran away from Gerald's abuse and left Christian behind. The three meet Christian's daughters, Melissa and Imogen, and learn that Christian is still furious with Elise. Hoping to patch things up, she hands Melissa a photo of the whistle to pass along to him.
Ted's hobbies, and Keyface's
That night, Elise and Tucker find a hidden room in the basement that holds a young woman Ted has kidnapped. Ted attacks them, and Specs kills him in self-defense. Once the police have cleared the house, Christian and his daughters walk in to look for the whistle, and Keyface goes after Melissa. This is the scare to brace for, and it happens in the middle of the movie: Melissa falls into a coma and her mind is stuck in the Further. Elise searches the house to help her and finds hidden suitcases with the belongings of many women who were held prisoner. She realizes Gerald did the same thing Ted did. Anna, the woman Elise saw as a teenager, was alive and trying to get away from her father. Keyface then ambushes Elise and her spirit is taken into the Further.
A rescue mission with a family problem
Specs and Tucker help Imogen, who has abilities like Elise's, enter the Further. Anna's ghost leads her to a prison realm where Keyface keeps every soul he has collected, Melissa and Elise among them. Elise realizes Keyface had been controlling Gerald and Ted and feeding on the fear of the women they held. Keyface tries to push her into hurting her father's spirit as revenge. She starts to beat Gerald but Imogen stops her, and Elise refuses to hand Keyface more hatred to feed on. Keyface takes Imogen's soul and attacks Elise, and Gerald tries to save her before Keyface stabs him and his spirit vanishes. Keyface then stabs Melissa, whose body convulses and flatlines. Keyface tries to possess Elise, but she blows Christian's whistle, and Audrey's spirit arrives and vanquishes Keyface.
The ending, explained
Audrey helps Elise, Melissa and Imogen escape the Further. While looking for the exit they open a door onto a ten-year-old boy, Dalton Lambert, sitting in his attic. It is the wrong door, and they leave it standing open. Melissa's spirit returns to her body, which saves her life, Elise makes peace with Audrey's spirit, and Elise and Imogen get back into their own. Christian and Elise patch things up. Later, a woman named Lorraine, whose son Elise helped years earlier, calls to ask for help with her grandson Dalton. Gerald is gone, Ted is dead, and Keyface has been beaten.
