Iain De Caestecker (Coronation Street) is Paul, a young man who is haunted by apocalyptic dreams that neither his therapist nor his best friend, Mac (Daniel Kaluuya, Skins, Sucker Punch), can provide answers for. Worse still, Paul has started seeing the Fades - the spirits of the dead - all around him. They're everywhere, but normally can't be seen, heard or touched - until now. An embittered and vengeful Fade has found a way to break the barrier between the dead and the living and Paul, Mac and their loved ones find themselves in the middle of it all. The worst is only yet to come as the fate of humanity rests in the hands of the two friends who already have enough trouble getting through a day in one piece, let alone saving the world.
