Gideon Falls.

Against his wishes, recovering alcoholic Father Quinn is assigned to lead a church in the small community of Gideon Falls. The previous pastor died, so Quinn is particularly disturbed when that same clergyman appears in his room one night. Chasing the allegedly dead man into a field, Quinn sees an ominous, abandoned-looking structure, which disappears after he finds one of his new parishioners murdered in the field. Meanwhile, in a big city also called Gideon Falls, Norton Sinclair is obsessed with searching through trash, convinced that he is uncovering the remnants of something terrible from his past, a mythical Black Barn. He collects and bottles nails and other specimens from the building, which he hopes to track down. His psychiatrist Dr. Xu is worried that Norton may require institutionalization again, but after she begins to receive her own visions of the Black Barn, she understands that whatever Norton is experiencing is more than psychosis. Together, the various characters are drawn toward whatever sickness lies within the Black Barn.
