Following a wild party, five friends are evicted from their student digs and are forced to seek refuge in an abandoned hall of residence in central London. They soon sense they're not alone and recall the story of a ritual group suicide that occurred in that same building a few years before. When they conduct a séance to uncover the reason behind the suicides, the answer comes not from the ghosts of dead students, but from the terrifying entity that drove them to their deaths. And now it knows they're here, it's not going to let them leave.
