The Taking of Deborah Logan

A team of students Mia, Gavin, and Luis begins shadowing Deborah Logan to document her daily routine. They set up at Deborah's home to capture her life as the illness progresses. The project is framed as a documentary about Deborah and her family.

As Deborah's condition appears to progress, the crew notes troubling patterns in her behavior. The local physician argues that these actions can be explained by Alzheimer's, not something supernatural. The tension between science and curiosity grows.

Luis records Deborah speaking in French about sacrifices and snakes, a moment that starkly shifts the crew's view of the events. The language suggests a meaning beyond medical symptoms. The footage deepens the suspicion of a darker influence at work.

They notice the switchboard line for 337 rings incessantly, a clue tied to Dr. Desjardins who vanished after a string of cannibalistic murders. The team begins linking Deborah's symptoms to a larger local history. The mystery deepens as they dig for connections.

The crew uncovers Desjardins' attempt to revive an ancient Monacan ritual that would grant immortality. The ritual requires the deaths of five young girls who recently began menstruating. The team begins to fear Deborah may be a vessel for this dark plan.

Deborah's increasingly dangerous behavior leads to her hospitalization for her safety. Gavin withdraws from the project in dismay, while Mia and Luis press on with the investigation. The stakes grow when the possibility of possession is considered.

The trio persists, developing the theory that a malevolent spirit is guiding Deborah to carry out the ritual. They push past the setbacks to continue gathering evidence. Their belief in a supernatural explanation intensifies the tension.

They learn Deborah had previously tried to abduct Cara Minetti, a young cancer patient. The revelation hints Cara could be a target for the ritual. The discovery deepens the sense that Deborah is connected to the danger surrounding Cara.

During a hospital visit, Deborah pleads with Harris Sredl to end her life; he tries to help but is knocked unconscious by the entity possessing her. Sarah discovers that Deborah learned Desjardins planned to use Sarah as the fifth victim, which drove Deborah to kill the doctor and bury the body in the yard.

Sarah and Mia locate the buried doctor's remains and attempt to burn them to stop Desjardins' influence. Desjardins' spirit interferes, thwarting their plan and preserving enough of the horror to continue haunting Deborah. The moment underscores that the danger is far from over.

Desperate, Deborah abducts Cara again and leads her toward the location where Desjardins killed his victims. Sheriff Linda Tweed trails after them, trying to halt the ritual's progress. The escalating pursuit culminates in danger for everyone involved.

In the chaos at the mine, Sheriff Tweed is killed as Deborah heads deeper into the underground. Sarah and Mia locate Deborah, stopping her from harming Cara at the last moment.

The trio manages to burn Desjardins' corpse, briefly restoring Deborah to awareness. In this quiet moment, Deborah and Sarah reconcile, though the danger remains and the fear lingers.

News footage reports that Deborah is unfit to stand trial and that her health deteriorated rapidly in the months after the incident. Cara, now 10 years old, celebrates her birthday, but a final image shows Cara with a cold, unsettling smile, hinting Desjardins' presence may haunt her.
