Honestly, the sheer amount of stuff that happens in the first section of 'It' is kinda staggering. The book opens with the murder of six-year-old George Denbrough in 1957, which sets the tone for everything that follows. We then jump to 1985, where Mike Hanlon, the only one of the Losers' Club who stayed in Derry, calls the others because the killing has started again. The narrative flips back and forth between their childhood summer in 1958—when they first battled the entity they call 'It'—and their adult return. The childhood sections are where most of the plot lives in this part: each kid has a terrifying encounter with Pennywise the Dancing Clown, who can shape-shift into their deepest fears. They realize they're all seeing the same thing and band together. The climactic moment of this 'chapter' is their first confrontation in the house on Neibolt Street, where they injure It with a makeshift silver slug and swear a blood oath to return if It ever comes back.
What always gets me is how the horror is just the vehicle. The real plot is about the end of childhood, the brutal bullying from Henry Bowers and his gang, and the intense, almost sacred bond of friendship that forms between these seven outcasts. The book’s structure means the adult sections in 1985 are mostly setup—the calls, the reluctant decisions to return, the creeping dread as memories surface. It’s less about a linear 'this then that' plot and more about the psychological excavation of trauma. The Neibolt Street fight feels like a victory, but it’s undercut by the promise of a future reckoning, which hangs over the whole thing.
