FRAILTY begins with Fenton Meiks, (Matthew McConaughey) a troubled-looking young man, has walking into an FBI office and claiming to know the identity of the serial killer known as "God's Hands." The story unfolds in flashback. Fenton describes growing up with his widower father (Bill Paxton) and younger brother Adam in a generally happy household. Then one night, he gets the boys out of bed to tell them that they're living in the End Times, and God has selected the family to seek out and destroy demons. The demons look like ordinary humans, but Dad knows the difference -- he can see their sins at the moment he dispatches them by touching them with his hands. He uses a divinely selected ax and a lead pipe to perform the actual "destruction" of the demons. Adam, the younger and more pious of the brothers, believes what his father tells him and immediately throws himself into the role of divinely appointed avenger. Fenton, older, keeps his doubts secret until his father actually drags home a bound woman, who he executes in front of his children. Fenton is horrified, but forced to take an increasingly active role in the "demon" hunting. Dad realizes it's difficult for his son to accept his new role in the universe. Nevertheless, as Fenton resists more and more, his father takes increasingly stern action.
