In Derry, Maine, four young boys once stood together and did a brave thing. Something that changed them in ways they hardly understand.

A quarter of a century later, the boys are men who have gone their separate ways. Though they still get together once a year, to go hunting in the north woods of Maine. But this time is different. This time a man comes stumbling into their camp, lost, disoriented and muttering about lights in the sky.

Before long, these old friends will be plunged into the most remarkable events of their lives as they struggle with a terrible creature from another world. Their only chance of survival is locked in their shared past
and in the Dreamcatcher.
