American technology horror trilogy, which began with a remake of Kiyoshi Kurosawa's 2001 Japanese horror film, Kairo.
When the dead discover a means to contact the living through electronic devices, cellphones and computers become open gateways to monstrosities and destruction.
The world has been reshaped by the invasion of ghosts via the wireless internet. Cities are deserted, technology has been destroyed and the few remaining human beings eschew anything electrical in order to avoid a confrontation with the soulless ghosts that now wander the planet. Most of the ghosts are doomed to a repetitive loop of something they did while they were still despairing humans (a man repeatedly hangs himself, for example), but there are some ghosts so locked in denial, they do not know they are dead. They continue to haunt their homes, wrapped in fear that their souls will soon be torn from them.
Seven years after the last attack by the "soulless ghosts" who haunted the human race twice before, the world is left void of all deadly electronics that almost destroyed it... or so we thought. Living a primitive existence on the outskirts of the city, human survivors are surviving without any trace of technology. That is until 16 year old Justine enters the city and, letting her curiosity get the best of her, opens a working laptop and unknowingly unleashes the most terrifying attack the survivors have ever faced. In a world already torn and without hope, can humanity make it through the toughest struggle of all time?
