The Devil's Chair is a British horror film. It premiered at the 2007 Cannes Film Festival. Nick West brings the easy and filthy Sammy to the abandoned Blackwater Asylum for using acid and having sex.
They find a weird chair and Nick proposes kinky sex to Sammy; however the device traps and kills Sammy. Nick is arrested and considered insane, being sentenced to the Hildon Mental Institute in spite of claiming that supernatural forces killed Sammy.
Four years later, the honorable Cambridge professor Dr. Willard proposes Nick's psychiatric Dr. Clairebourne to release him under his custody for an experimental treatment, exposing the truth to Nick bringing him back to the crime scene.
Dr. Clairebourne opposes, explaining that Nick still has severe delusions, but in the end she accepts, with Dr. Willard assuming full responsibility for Nick. Dr. Willard, his assistant Melissa and the students Rachel Fowles and Brett Wilson head with Nick to the Blackwater Asylum finding the dreadful truth about the devil's chair.
