Four priests exiled to a small Chilean seaside town to atone for the sins of their pasts find their fragile stability disrupted by the arrival of a newly-disgraced companion in this taut blackly comic drama.

Inspired by true events, this supernatural thriller follows a seminary student sent to study exorcism at the Vatican in spite of his own doubts about the controversial practice and even his own faith. Only when sent to apprentice with legendary Father Lucas, who has performed thousand of exorcisms, does his armor of skepticism begin to fall. Drawn into a troubling case that transcends even Father Lucas's skill. Includes chilling alternate ending.
