Hadji, a young man living humbly on the banks of the Ganges River and in desperate straits after losing all his possessions, is accepted as a disciple by a mysterious spiritual guide.

At the beginning of the 20th century, a series of Gnostic spells perpetrated in India affected a Spanish priest, ending his honor and his life and cursing his offspring forever. Harassed by this spell, his great-great grandson, also a priest, is forced to flee from the town to the capital and from there to a cathedral submerged in the depths of the ocean. Black magicians, delinquents, insects, archons and even Satan himself will be some of the sinister characters he will have to face in order to succeed in his evangelizing adventure.
