The Rookie team investigates the disappearance of Abigail Tierney
The case in The Rookie season 7 episode 15 kicks off when a documentary crew returns to film a new project, this time focused on the sudden disappearance of Abigail Tierney. Nolan is personally affected, as Abigail was once engaged to his son, Henry. Though their relationship ended amicably, her vanishing stirs concern.
Abigail had ghosted friends and family while working on a true-crime documentary about the Westview Psychiatric Hospital, known for its dark history. Initially, her disappearance wasn’t taken seriously due to her pattern of cutting off contact. However, suspicions turn toward Carl Ditweiler, a cameraman and former hospital employee.
He denies knowing Abigail and flees when confronted, but evidence quickly exposes his obsession with her. Photos, footage, and his past involvement at the hospital place him at the center. With Carl in custody and the investigation reopened, the LAPD begins to unravel a much larger conspiracy hidden inside the abandoned hospital.
The Rookie season 7 episode 15: What are the secrets behind Westview Psychiatric?
In The Rookie season 7 episode 15, Westview Psychiatric Hospital, long abandoned and rumored to be haunted, holds the key to Abigail’s disappearance. Originally used in the CIA’s MK-Ultra program, the facility saw mind-altering drug experiments before it was shut down and repurposed as a psych ward.
During her documentary project, Abigail uncovers disturbing stories about patients getting worse, not better, suggesting the hospital retained a dangerous legacy. Drug residues from past experiments seeped into the building, affecting anyone who spent extended time inside, including Abigail, Nolan, Tim, Lucy, and Carl.
While investigating, the LAPD discovers a hidden lab sealed behind a wall, where Abigail had been trapped for two weeks. She survives by rationing trail mix and protein bars left behind by Bob, a private investigator who died months prior. The hospital’s secrets also expose Meg Davison, a corrupt therapist exploiting her patients for profit. This ties the facility’s haunted reputation to real criminal abuse and psychological manipulation.

In The Rookie season 7 episode 15, the returning documentary crew initially sets out to capture Abigail’s story, but ends up uncovering more than they imagined. Their footage, including Carl’s original recordings, plays a crucial role in locating Abigail. Enhancing background audio from her last known video reveals a voice that hints at her exact location.
With the help of YouTube ghost hunters, the LAPD follows mysterious sounds to a hidden wall inside Westview. Nolan tears it down and finds Abigail alive but disoriented, affected by the hospital’s contaminated water supply. As the truth surfaces, Abigail takes control of her narrative, interrupting the documentary crew’s interviews to announce her own plans to tell the story.
Her testimony and footage implicate Davison, the corrupt therapist behind Bob’s murder and a twisted financial scheme involving conservatorships and drugging patients. The documentary crew’s return not only brings the case full circle, but it also ensures Abigail’s voice and the victims’ truths are finally heard.
