Taking place in the present day as well as decades in the past, the story revolves around members of The Loser's Club, now adults returning to the hometown where they were once haunted by a mysterious creature in the form of a clown called Pennywise. The creature, known only as It, preyed upon the children of Derry, Maine, and isn't willing to let its former enemies – who had once come together to defeat it as children – vanquish its evil once again.
