Demonic (2021)

She meets scientists Daniel (Terry Chen) and Michael (Michael J. Rogers) who explain Angela fell into a coma following a series of violent episodes in prison and is "locked-in" inside her body. They tell Carly that Angela is highly active inside a simulation, calling for Carly and Martin. The simulation involves a 3D virtual model being controlled by one individual and sent into the mind of another individual. They ask Carly if she is willing to enter Angela's mind to talk to her, which she reluctantly agrees to do so. In the simulation, Carly enters a copy of her childhood home and angrily confronts Angela about her crimes. Angela, fully able to speak in the simulation, demands that Carly leaves. Post simulation, Carly is interviewed about her experience by Daniel and Michael. They try to persuade her to go into the simulation again but Carly is hesitant, returning home. That night she has a nightmare where she finds a strange symbol made of a raven carcass.

Carly arrives at Therapol for another trip inside the simulation. This time she enters through a new tunnel into a field outside an old sanatorium which Angela had worked at. She meets with Angela who claims that she was not the person who called for Carly and Martin. Angela's body in the simulation starts to glitch out and the scientists ignore a terrified Carly's demands to be removed from the simulation. Entering the sanatorium, she finds Sam's body before being attacked by an Avian like Demon who slashes its arm open, creating the same cut on Carly's real-life body. Carly exits the simulation and tells Daniel and Michael how years ago, she and Martin found Angela in the sanatorium with the same cut on her arm. This preceded Angela's descent into madness where she made the same symbol Carly saw in her nightmare. Carly refuses to participate in another simulation and leaves Therapol. She calls Sam and is relieved to hear that she is fine.

Carly visits Martin and tells him about her experience. He shows her his theories about demonic possession, showing Carly a sketch of the creature she saw in the simulation. Martin claims to have suffered similar nightmares that Carly suffers from and explains how the demon manipulates its target through their family and friends. He also tells Carly of his theory that the Vatican is funding special black ops groups consisting of priests. The Vatican buys companies like Therapol to detect genuinely possessed people who seemingly suffer from medical conditions before the squad eliminates the demon by bringing it to its entry point from hell. In the case of the supposed demon taking over Angela, this is the sanatorium. A bewildered Carly refuses to believe in this theory and returns home. Martin begins to suspect the demon has latched onto Carly.

That night, a concerned Sam pays Carly a visit and Carly sends her away. Sam returns later into the night this time with a bird mask and telling Carly "to look for me in the woods". Sam puts on the bird mask and suddenly contorts her body, chasing Carly around the house. Carly barricades herself in her bedroom where she is attacked by the demon. Carly wakes up, the events are seemingly a dream and she rushes to Sam's house. It is revealed that Daniel and Michael are watching her and that Martin's theory is correct: they are priests and plan to eliminate the demon at the sanatorium. The demon has become obsessed with Carly while trapped in Angela's comatose body and wants to possess her to commit the same crimes it made Angela do. Carly finds Sam missing from her house and recruits Martin to help rescue her. They travel to the woods and retrieve a traumatized Sam who claims a group of men took Angela into the nearby sanatorium. They leave Sam in Martin's car and head out to find Angela.

At the sanatorium, they find the black ops team has been massacred and stumble upon a dying Daniel. Daniel explains how the demon has entered Michael who killed the squad and gives Carly a holy lance that will kill the demon. In the sanatorium, Carly enters the simulation to rescue Angela. She finds Angela who is finally free of the demon and she makes amends with her daughter before dying peacefully. Carly escapes the simulation and looks for Martin who has gone missing. She stumbles across his car which is now in flames as well as Sam's burnt corpse. Carly finds Martin being tortured by Michael who pursues Carly. Carly stabs Michael with the lance, killing him and accidentally sending the demon into herself. Carly wrestles with the possession before stabbing herself with the lance, killing the demon.

Sometime later, Carly awakens in a hospital and makes amends with Martin. She leaves flowers at Angela's grave.
