In Asylum, Sister Mary Eunice is a sweet, innocent nun at Briarcliff Manor . . . that is until she becomes possessed by the devil when a teenage boy gets exorcised at the sanitorium. Besides killing a handful of people, the devil terrorizes Sister Jude (Jessica Lange), taking her place of power and even framing her for killing the head of security at Briarcliff. Eventually, the real Mary Eunice is able to beg the Monsignor (Joseph Fiennes) to let her die. The Monsignor pushes her off the stairway, and the Angel of Death (Frances Conroy) comes to collect her soul and the evil spirit.
