A malevolent force in a small New England town takes the shape of a clown, but he's not clowning around. Instead, he terrifies youngsters and brings some to their untimely doom - until some wily kids fight back. The evil resurfaces 30 years later: meaner, angrier, deadlier. And friends who vividly remember youthful terrors reunite to battle It. Based on the 1986 novel.
