Mortal Sins (TV)

Cops find themselves dealing with a string of homicides with a twist, each victim was given the last rites, this leaves local priest Father Thomas Cusack to startlingly conclude that it can only be the work of someone linked to the church. When the suspect begins confessing his sins to Thomas, he knows it must be a seminar student who's suffered a severe crisis of faith. Unable to aid the police due to his oaths, he decides to do what he can to understand why this would-be man of the cloth has become so twisted.
