Alien Footprint Castings

The season begins in 1964 at the fictional mental institution, Briarcliff Manor, following the stories of the staff and inmates who occupy it, and intercuts with events in the past and present. From the 2012 season American Horror Story: Asylum Episode 9 “The Coat Hanger”, this is Dr. Arden’s castings of Alien Footprints. "They were here. The creatures you told me about. The little green men. Except, of course, they're not green, are they, Mr. Walker?" Dr. Arden has something to show Kit. Something he found down in the dark, in the tunnels beneath Briarcliff. These are seen when Dr. Arden convinces Kit to temporarily die and force the aliens to return, only to find out that the aliens saved Grace's life and she is pregnant with Kit's baby.
