Sanatorium is a horror movie that follows a paranormal investigations team as they explore the abandoned Hillcrest Sanatorium in search of evidence of the afterlife. The team consists of five members, each with their own unique skillset. There is the leader, John, who has years of experience in investigating paranormal activity; the tech guy, Craig, who is responsible for setting up cameras and other equipment; the psychic, Sarah, who can communicate with spirits; the skeptic, Alex, who is there to debunk any paranormal claims; and the newcomer, Emma, who is excited to join the team for her first investigation.
Once they arrive at Hillcrest Sanatorium, they are immediately struck by the eerie atmosphere. The building is run-down, and the only sound is the howling wind outside. As they begin to set up their equipment, strange things start to happen. Doors slam shut, shadows move across the walls, and cold spots can be felt throughout the building.
As the night wears on, the team starts to experience more and more supernatural activity. Sarah becomes possessed by a spirit, Emma disappears, and Craig's equipment stops working. John, Alex, and Craig are left to investigate the building alone, trying to find their missing teammates and figure out what is causing the paranormal activity.
As they navigate the dark corridors, they come across evidence that the sanatorium may have been involved in some dark and twisted experiments. They also discover that they are not alone in the building, and that there are other entities at play.
In the end, Sanatorium delivers a heart-pumping climax that leaves the audience on the edge of their seats. It is a tale of terror and suspense that will leave viewers questioning their beliefs in the afterlife.
