Kelly visits her nephew Andy, who is under the care of Dr. Alice Farrell. Andy is drawing crayon pictures of his experiences, including a man dressed in brown carrying a knife. Kelly tries to get Andy to say something, but all he does is make a sketch of a woman. The agent realizes that it's her sister, Meadow, and asks why the head is bloody. Andy finally says that his mother cut her hair out, and remembers the two locked in the trunk of the red Valiant until Billy comes to get them.
Sky returns to her desk at the studio and finds Peter there, using her laptop. He explains that his computer was down and he needed to check an important email, and then welcomes her back after her hospital stay. Skye motions him out of his seat and he notices that she's wearing a good dress. He asks if she'd like to share something with him and Skye finally tells him that she's going to the wake of Jeff's editor. Bert.
At the wake, Jeff eulogizes Bert for the gathered employees. Afterward, E.J. approaches him and says that she knows that Bert's death wasn't an accident. She figures that it's related to how he stopped her from hacking the police files and getting Sakelik's address. To get revenge on Sakelik, E.J. has hacked her records and gives the printouts to Jeff. He makes her promise not to do it but E.J. warns him that he's the one in danger.
As E.J. walks away, Sakelik arrives and Jeff rolls up the files before she can see them. The detective inform Jeff and Skye that she'll be handling the investigation into Bert's death personally, and then congratulates Skye on her recovery. When Jeff accuses her of murder, Sakelik ignores him and insists that Bert's death was a home invasion gone bad. Jeff tells Sakelik that the wake is a private affair. As she turns to go, Sakelik promises them that she won't let it go.
That night, Jeff and Skye go through Sakelik's files, and Skye insists on pursuing the matter and learning the truth about her father. Jeff discovers that Sakelik tried three times in the last year to have her juvenile records expunged, and they figure something happened in the last year to make her extra-cautious. The reporter contacts Detective Marsh, Sakelik's ex-partner, and uses some evidence he has on Marsh of witness tampering to get him to hand over Sakelik's files. As Marsh leaves, he admits that he never thought that Jeff would stoop to blackmail.
The next day, Roger is leaving the studio after filming when Stuart pulls up in a c car. He reminds Roger that they met at the studio promo party and Roger admires the car. When Roger wonders why Stuart is there, the man explains that he bought on office on the lot and is getting into movie production.
Stuart invites Roger to check out a project that he's considering and gives the actor his card, and Roger says that he'll think about it.
Sakelik returns to Bert's apartment and finds her partner, Zavala, going over the crime scene. He doesn't believe that it was really a home invasion, reminding Sakelik of a case she cracked where a husband killed his wife and made it look like a home invasion. Sakelik insists that there's nothing to her partner's suspicions and advises him to drop it.
Skye and Jeff go to Fandomain and go over Sakelik's files. They find a reference to an arrest in 1988, but the files refers to an abandoned child, not a criminal arrest. They realize that the photo of the girl is Sakelik but there are also photos of other children. Jeff finds an address in Arrowhead in the file and they head out.
Sakelik goes to a video store and meets with the wheelchair-bound owner, Louis. He wonders what she's done now and the detective explains that she murdered an innocent man to send a message to someone threatening their work. Crying, Sakelik takes Louis' hand and says that what she had to do is hurting her. Louis asks what Stuart has said and Sakelik tells her friend that she hasn't said anything. She assures Louis that Stuart is certain that what they've been praying for years is almost ready to begin.
Jeff and Skye drive to the address while confirming that it now belongs to Annabelle Creusen since 2003. Annabelle greets them and they ask about the history of the house, which has a sign out front naming it "Moon Hill." Annabelle says that she named it herself and explains that she bought it from a couple, the Danners, and before that the county owned it. When she wonders why they're there, Skye shows her a photo of the teenage Sakelik. Annabelle claim she doesn't recognize her and invites them to look around. As they walk around, Annabelle nervously pulls down her sleeve to cover a tattoo of three bars.
Billy is at the town courthouse giving a speech promoting his new children's shelter. Kelly and Paz arrive, listen briefly to the speech with disgust, and then serve a warrant on the cultists guarding Billy's red Valiant. They check the trunk and Kelly finds a hank of Meadow's hair inside. Now that they have the evidence they need to confirm Meadow was in the car, they go over and arrest Billy on charges of kidnapping and child endangerment.
Annabelle comes to the video store to meet with Louis and asks if Sakelik is dong something again. Louis is busy watching video of the house when they were there as children, and reminds his visitor that Sakelik was the one who protected the younger children. Annabelle worries that Sakelik can be dangerous, as they both know from one particular evening, and worries that Sakelik might finally have snapped. Louis points out that Annabelle bought the house in an attempt to live in the past, and admits that none of them can escape their past. Annabelle realizes that Sakelik came to see Louis and he admits that the detective confessed to killing someone to further Stuart's goals. Annabelle wonders what could justify murder and Louis tells her that what they've been striving for will finally come to pass.
Jeff and Skye go back to Jeff's apartment and check the Arrowhead newspaper from the 1980s. They find a series of articles about complains filed against the people living in the house, including accusations of truism. All of the articles have photos of children but no parents, and Jeff suggests that someone used the house as a gathering place for a cult. They enlarge the 1983 photos and find one that shows the name Moon Hill... even though Annabelle claimed she named it that in 2003 when she bought the house. One photos has a girl that looks like a younger version of Annabelle.
Zavala seeks out Marsh at the police station and asks why he requested a new partner. Marsh insists that Sakelik was spooky but doesn't go into any details. Sakelik goes out to her car and sees them talking, and Marsh hurriedly walks away. Meanwhile, Louis approaches Sakelik and warns her that Annabelle came to see him after people asked about the house. He's sure that Annabelle didn't tell them anything, but tells Sakelik that he told her that Stuart's plan was reaching fruition. Sakelik, furious, reminds Louis that Annabelle rejected them and he admits that he's worried that she might tells someone about what Stuart is doing. When he worries if he did the right thing warning her, Sakelik assures him that she'll take care of Annabelle.
As Jeff and Skye drive back to Arrowhead, they speculate on whether Sakelik became a True Believer with Cult because she was raised by a cult... and wonder how many of the children at the house may also be True Believers.
Roger leaves the studio after a day of filming and discovers Stuart's car parked in his spot. When Stuart comes over, Roger asks him to move the car and Stuart informs him that it's Rogers. Stuart assures him that money is no object to him and gives Roger the keys. The key tag has Stuart's company name on it, and Stuart explains that his family has been in the cutlery business for a hundred years. Stuart assures the actor that he is only giving him the car in the hope that he'll consider working with him on a film project once Cult shuts down for the hiatus. Roger doesn't agree, and Stuart receives a call and steps away to take it.
That night, Jeff and Skye approach and discover that all of the lights are out. Annabelle emerges from the woods, pointing a shotgun at them, and Jeff tells her that they know all about her history at the house with Sakelik. When he mentions the cult, Annabelle insists that they were a family, banding together after their parents left them. The twenty children in the house hoped that their parents would come back. When they didn't, Sakelik took control and indulged her cruelty.
Kelly assigns Billy to an interrogation room and comes to talk to him. He reminds her of all the times when she was a Blood member that they made love together. Kelly focuses on the case and tells him that they confirmed that the hair belonged to Meadow. Billy points out that the car isn't registered to him but Kelly figures that they have enough evidence to make some arrests among the cult members and pressure someone into talking. Billy ignores her accusations and asks why she left him, and Kelly says that he lies to everyone, including himself. When he lowered his guard around her, she saw his lies for what they really wear. Kelly offers Billy a deal: freedom for Meadow's return. However, an aide comes in and tells her that Billy has been released after his lawyer filed an appeals. As Billy leaves, Kelly warns him that it won't end until she has Meadow back.
Annabelle leads Jeff and Skye behind the house to a statue and explains that once they were on their own, the older children broke into homes to steal supplies. Eventually they started taking more. Annabelle has Jeff move the statue, revealing a hole beneath containing a box. Inside the box is an old map to the stars' homes, covered in blood, and Annabelle asks if they remember the Olivia Leland murder. Jeff remembers that Olivia was a TV actress murdered 25 years ago in her Beverly Hills home. Annabelle explains that Sakelik used the map to pick out targets and took Annabelle and two other children with her to rob Olivia's home. Olivia returned unexpectedly and Sakelik killed her. As they talk, Sakelik fires from the shadows, killing Annabelle. As Jeff and Skye run to their car and drive off, they see Sakelik fire several more rounds to make sure that her former friend is dead.
At the studio, Peter tries to go through Skye's desk. When he discovers that the drawers are locked, he calls "Mr. Right" and tells him that he hasn't found anything interesting. He promises to call back if he does.
When they get back to his apartment, Jeff vows to make Sakelik pay for killing Bert and Annabelle. They kept the map and Jeff figures that they now have leverage against Sakelik to force her to take them to Nate. Skye examines the box and finds a photo tucked into one side. It shows several of the children gathered around a red Valiant, identical to the one on Cult. Since Steven Rae is the one who incorporated the car into the show, they wonder if Rae was one of the cult members.
