Frailty

FBI Agent Wesley Doyle is approached by a man who claims to know the truth behind the serial killings he is investigating. He begins recounting his childhood in the 1970s, when his father told him and his younger brother that an angel had shown him people who were actually demons. Convinced that these beings had to be destroyed, their father involved both boys in his mission, forcing them to confront a frightening question: were they witnessing divine visions or the collapse of their family into violence?
