Virtual network is not only a refuge from stress and pain, but also a hell road to destruction. 17-year-old William (Aaron Johnson Aaron Johnson) sets up a chat room online, and soon after that, Eva (Imogen Potts Imogen Poots), Jim (Matthew Bild Matthew Beard), Emily (Hannah Murray Hannah Murray) and Mo (Daniel Carua Daniel Kaluuya) gather here one after another. They talked freely and poured out their troubles. William listens to them like a wise man who has experienced many vicissitudes, but he doesn't know that his life is coming to a dead end. And Jim's distress seems to be the beginning of all the chaos. The film is adapted from the Irish playwright Enda Walsh's stage play of the same name, directed by Hideo Nakata, a famous Japanese horror film director.
