The universe is vast and in its unending depths lay the truth too terrifying for mankind to even attempt to grasp; we are not alone. From the jungles of South America a group of investigators return to the concrete jungles of New York City at the behest of their former compatriot. The alleys and streets of the city are just as barbaric as the jungles of their previous adventure. New allies, a death cult and adventure await. Who is behind the strange adventures plaguing our investigators and what lies behind the Masks of Nyarlathotep?
