A series of gory, violent and gut wrenching murders are taking place in the dull and calm town, nobody has an idea of who it could be
Or what it could be
With the help of a 15 year old genius with many untold secrets, Father Samson Raiden, a priest and a teacher at a local catholic school, was brought in on behalf of the Vatican to restore peace and stop the murdurer, with the help of Katie Eldritch, they crack down on the killings, however there is a darker truth to the mass murdurer and stalker
Is it a stranger or is it someone closer? It could even be you or me
