Premise: The second season of ``American Horror Story'' takes place in 1964 in Briarcliff Manor. Briarcliff is a former tuberculosis ward that is now an insane asylum run by a group of nuns led by head warden Sister Jude, a troubled woman with a dark past that begins to resurface. Danger lurks around every corner at the locked-down facility that houses everything from Nazis and serial killers to mutants and aliens. Yes, aliens. With that mix of patients, not to mention the staff, no one is safe inside the building's walls.
