The doomed are no longer content to burn in hell and there is one man they must destroy in order to be free; the pastor Father Jacob. Father Jacob has been appointed by the Vatican as an exorcist, a task he reluctantly takes on and turns out to be more difficult than he ever dared to think. When his apprentice Vimal is brutally murdered, the game becomes increasingly dangerous for Jacob. He must find his way between the terrifying world of demons, the political and hierarchical power play of the Church and the cynical London police, while fighting for his life.
