In 1866, a young doctor is summoned by his uncle to a remote town in the Ozarks only to discover upon his arrival that the utopian paradise is not all that it seems to be.

It's 1999 and over the course of one 12-hour shift at an Arkansas hospital, a junkie nurse, her scheming cousin and a group of black market organ-trading criminals start a heist that could lead to their collective demise.

On Halloween night, two young women leave a party to venture into the woods in search of their friend, who has mysteriously disappeared. They stumble on a vast ruined building that shouldn't be there - when they go inside, they soon realize that they shouldn't be there either.
