An unorthodox college professor (Jared Harris) leads his best students (Sam Claflin, Olivia Cooke, Erin Richards, Rory Fleck-Byrne) off the grid to perform a dangerous experiment to create a poltergeist. Operating under the theory that paranormal activity is triggered by negative human energy, the group uses a series of tests to push a young woman to the edge of sanity. Frightening occurrences with unspeakable consequences subsequently unfold, leading the researchers to the realization that they have unleashed a force more terrifying than they could have imagined. Written or directed by John Pogue.
