Father Barrera is a disgraced priest, haunted by his part in the tragic death of a child. As penance, he is exiled to the remote South American town of Puerto Cristina to apprentice under the enigmatic Father Stygian, controversial exorcist.

Exorcists are normally trained in the Vatican, but Stygian has his own way of handling demons... methods that predate even the Church. And unfortunately for Barrera, Stygian's last apprentice committed suicide not long ago.

As Barrera seeks to unlock the mysteries of Stygian's strange practices, he uncovers an island rife with evil and supernatural phenomena.

What do these possessions mean, and how are they connected to a mysterious hospital patient, one who's been in a coma for nearly half a century without aging a single day...
