2006 British horror. Looking for an out-of-the-way venue for a sex and drugs session, Nick West (Andrew Howard) brings his girlfriend Sammy (Polly Brown) to the disused Blackwater Asylum. Finding a chair which looks like a cross between an electric chair and a bizarre sexual toy, they cannot resist the temptation to try it out. Polly is trapped and killed and Nick, protesting his innocence and claiming that supernatural forces were to blame for Sammy's death, is locked away in an asylum. Four years later, Nick is taken back to Blackwater by his psychiatrist Dr Clairebourne (Nadja Brand) and eminent Cambridge professor Dr. Willard (David Gant). As they try to uncover the strange secrets of the Devil's Chair, the nightmare continues.
