Kenny has been raised within the The Brethren, an Evangelical sect who preach purity, morality, and unwavering allegiance to the word of God. A security officer by day, he spends his nights stalking and strangling 'immoral' women thus, he believes, cleansing them of their ungodly transgressions. But when a new nurse is assigned to help care for his ailing mother, she soon becomes suspicious of the activities of the church, unwittingly bringing her closer to unleashing Kenny's unholy wrath against her.
