There's something sinister under the surface of the idyllic, suburban town of Wesley Falls, and it's not just the abandoned coal mine that lies beneath it. The summer of 1995 kicks off with a party in the mine where six high school students witness a horrifying crime that changes the course of their lives.

Twenty years later, Jia calls them all back to Wesley Falls—Maddy has been murdered, and they are the only ones who can uncover why. But to end things, they have to return to the mine one last time.
