Inspired by real events, The Quiet Ones follows Professor Coupland (Jared Harris), a charismatic, unorthodox Oxford academic who recruits student Brian McNeil (Sam Claflin) and some classmates to carry out a private experiment to create a poltergeist and hopefully crack the key to curing certain negative aspects of the mind. Their subject: an alluring, but dangerously disturbed young woman (Olivia Cooke). Their quest: to explore the dark energy that her damaged psyche might manifest.
As the experiment unravels, along with their sanity, the rogue PhD students are soon confronted with the terrifying reality that they have triggered an unspeakable force with a power beyond all explanation. As anyone who has ever seen a horror film, or knows anything about the supernatural will tell you, tangling with such dark forces is pretty much a one way trip to crazy town, with added screaming and usually death.
The Quiet Ones is out on 11 April.
