Frailty is a 2001 American psychological horror film directed by and starring Bill Paxton, and co-starring Matthew McConaughey and Powers Boothe.

The plot focuses on the strange relationship between two young brothers and their father, who believes that he has been commanded by God to kill demons disguised as people.

In his office in Dallas, FBI Agent Wesley Doyle is visited by Fenton Meiks, who says his brother Adam is the culprit in the "God's Hand" serial killings.

While children in the summer of 1979, their father, a mechanic, told them he had been visited by an angel and tasked by God with "destroying" demons disguised as humans; a mission which must be kept secret.

Fenton then explains how they took the second victim (a supposed child molester) in broad daylight, with his father insisting God would blind any witnesses.

Their father is grief-stricken over having to kill an innocent man, and angry with Fenton for forcing him into it due to his lack of faith.

Adam did in fact share his father's visions, and it is revealed that their victims were; at least, guilty of terrible crimes, including child molestation and murder.

At Thurman, Agent Hull visits Adam, who is actually the county sheriff, to tell him Fenton was the God's Hand killer.

In October 2000, it was announced that Lions Gate Films would fully finance Bill Paxton's directorial debut, Frailty.

Besides 'finding' the property and foisting in on Bill, I may have made small contributions to the script in the final stages of development, but I wouldn’t want to take anything away from the sole author, Brent Hanley, nor chief producers Paxton, David Kirschner, and Corey Sienega..."[4] Review aggregator website Rotten Tomatoes reported that 75% of 155 critics gave the film a positive review, with an average rating of 6.9/10.
