In 1962, amid a spate of unexplained disappearances of local children, a group of misfit friends begin to suspect a long-buried ancient evil lurking. As the kids set out to determine what's really going on, a rising unease prompts several townspeople to work together to restore peace – all while a U.S. military operation seeks to exploit Derry for its own objectives.
