The sequel to 2017's adaptation of the Stephen King thriller sees the Losers' Club grown into adulthood. For many of them, the horror of their encounter with Pennywise the Clown is a half-buried childhood memory. But Pennywise still lurks beneath the town of Derry, and he's beginning to stir again. Inevitably, the Losers are drawn back to Derry to face the terror of their childhoods and, perhaps, put an end to Pennywise entirely... if they can survive a second meeting with him.
