The evil one has sent a powerful Jackal to this dimension, his son, to be confused among men.

The mission of the Jackal is to enforce a prophecy written more than 200 years ago, which points to the moral and religious destruction of a great metropolis, New York.

To fulfill the objective, the Jackal recruits men, in different ways, and turns them into vassals at the service of darkness, to spread the plague.

An old secret organization, called "The Council", fights against the power of the Devil, and tries by all means to end the word of evil, written in black books.

It is a journey that will take emotions to the limit and make you reflect on the behavior of people in an environment dominated by vanity and consumerism, where moral values are a facade and ethics is a price as solid as personal convenience.
