IT: Welcome to Derry (2025) serves as a chilling prequel, transporting viewers decades before the events of the original films to uncover the cursed origins of the town of Derry, Maine. The story begins in the late 1950s, when a group of families arrives in Derry seeking new beginnings, unaware that the town itself feeds on fear. Beneath the postcard-perfect streets lies a malignant presence that awakens every 27 years, shaping Derry’s history through tragedy and silence.
The narrative follows a group of teenagers who begin noticing unsettling patterns—children going missing, adults behaving strangely, and violent incidents quickly forgotten by the community. As they investigate, they uncover disturbing connections between present-day horrors and past catastrophes, including fires, massacres, and unexplained deaths. Their curiosity draws the attention of a shape-shifting evil that preys on their deepest fears, slowly revealing itself in terrifying forms.
Unlike previous stories, this season emphasizes how Derry itself is complicit in the evil. Authority figures dismiss evidence, neighbors look away, and trauma becomes normalized. The monster’s influence spreads beyond individual victims, corrupting the town’s collective conscience. The teenagers realize that the creature does not just hunt—it controls memory, silence, and denial, ensuring its survival through generations.
As fear escalates, the group discovers ancient clues suggesting that this evil existed long before Pennywise took a recognizable form. Native legends, old newspaper clippings, and forbidden rituals hint at a cosmic entity bound to the land itself. Attempts to fight back come at a devastating cost, as friendships fracture and some are lost to madness, disappearance, or death. Courage becomes an act of defiance in a town designed to erase it.
The season builds toward a haunting conclusion in which the survivors confront the creature—only to realize that defeating it completely is impossible. Their actions may weaken it, but the cycle remains unbroken. IT: Welcome to Derry ends on a chilling note, revealing how the town resets, memories fade, and evil waits patiently beneath the surface—setting the stage for the horrors that will return decades later.
