Shelby Oaks (2024)

Paranormal investigator YouTubers Riley Brennan, Laura Tucker, David Reynolds, and Peter Bailey—collectively known as the Paranormal Paranoids—go missing while investigating a prison in the ghost town of Shelby Oaks. The bodies of all but Riley are found, and one of their two cameras is recovered, containing footage of a terrified Riley.

Twelve years later, Riley's older sister, Mia, is interviewed for a documentary about Riley's disappearance. Mia asserts her belief that Riley is still alive, and recounts that Riley often experienced night terrors as a child and believed something was watching her. Mia's marriage to her husband Robert is under strain in the wake of the Paranoids' bodies being discovered, compounded by their failure to conceive a child. After the documentary crew leaves, a stranger arrives at Mia's door and says "she finally let me go" before shooting himself in the head.

Mia retrieves a mini-DV tape labeled 'Shelby Oaks' from the man's body. The tape reveals the Paranoids investigating the prison along with an abandoned amusement park. They are attacked and Laura, David, and Peter are killed by the man, who also captures Riley before the footage cuts out. Mia later sees a dog with glowing eyes outside her home.

She interviews the former prison warden, who reveals that the man is Wilson Miles, a violent offender. After Miles arrived at the prison, a riot erupted, during which a computer malfunction opened every cell, though Miles stood in place and stared out his window instead of leaving. Mia finds a book in Riley's belongings describing demonic symbols. After doing more research and learning about parasitic incubi and hellhounds, she becomes convinced that Riley was the victim of an occult ritual. Exasperated by Mia's obsession with solving Riley's case, Robert leaves her.

Mia goes to the prison, finds Miles' former cell, and looks out the window. She sees the ruins of the amusement park in the distance, before being attacked by a hellhound. She flees to the amusement park, where she encounters another hellhound and comes across a dilapidated farmhouse, where she meets the home's elderly occupant, Norma.

In the house, Mia finds evidence that Norma is Miles's mother, and that Miles kidnapped Riley. Under the influence of Norma, a devotee of the incubus Tarion, Miles repeatedly raped Riley in an effort to conceive a child until, after many miscarriages, Riley finally gave birth to a healthy baby boy. Mia texts Robert to send the police to her location. Norma leads her into the basement, where Riley is imprisoned. Mia frees her, but rather than leave, Riley seizes a fire poker and goes upstairs. Mia witnesses Norma incapacitate Riley before performing a blood ritual over Riley's newborn son and glimpses Tarion. Norma dies from blood loss and Mia lovingly greets the infant as the police arrive.

Riley and the baby are taken to the hospital and discharged soon after. That night, Riley attempts to smother the baby until Mia stops her. Riley insists the baby is possessed and must die. In the ensuing struggle, Mia accidentally pushes Riley out the window. She survives the fall, but is surrounded by hellhounds and devoured. Mia realises that Riley's childhood belief that something was watching her was actually Tarion, observing both of the sisters, intending one to bear his child and the other to raise it. Tarion appears behind her and grasps her shoulders. Mia's eyes glow and she screams.
