A man, portrayed by Richard Dreyfuss, finds himself in his car perusing a newspaper headline detailing a brutal stabbing at a fast food joint. Overcome by nostalgia, he recalls his childhood and the significant event when he first encountered death at the tender age of 12.
The story centers around Gordon "Gordie" Lachance, played by Wil Wheaton, who is indulging in a game of cards within a treehouse alongside his closest pals Chris Chambers and Teddy Duchamp, portrayed by River Phoenix and Corey Feldman, respectively. Each boy carries a unique backstory and reputation. Chris, burdened by his troubled family’s reputation for dishonesty and violence, strives to be a better person while grappling with the long shadow of his lineage. Teddy, with a somewhat oddball essence, bears the physical scars of his father's instability, having been burned by him during a time of great distress. His father resides in a mental institution, yet Teddy speaks proudly of him as a war hero. Meanwhile, the overweight Vern Tessio, played by Jerry O'Connell, desperately seeks entrance into their game, claiming to have crucial news. The group falls silent when Vern mentions having overheard that his brother Billy and a friend found the body of Ray Brower, a boy who had gone missing. The boys are instantly intrigued, realizing that Ray was their age and had vanished while blueberry picking.
Driven by the desire for adventure and the prospect of being local heroes, they plan to locate the body, convincing their parents that they'll have sleepovers at each other's homes. As morning dawns, Gordie confronts a stark reality—his older brother, Denny, has died in an accident, and his family is emotionally fractured. His mother is silent, and his father harshly compares him to Denny, expressing disappointment in his aspirations to be a writer.
Gordie's journey unfolds as he and Chris stumble upon a gun that Chris has stolen from his dad. What ensues is a harrowing encounter with a gang led by Ace Merrill, played by Kiefer Sutherland, who menaces them but ultimately allows them to go free. As they trek to the train tracks with hopes of adventure, they almost meet with tragedy when Vern loses his comb on the bridge, leading to a panic-filled escape just ahead of an oncoming train.
On their quest, the boys face various adventures, including a near-collision with the infamous dog Chopper at a junkyard. Much to their horror, a confrontation at the leeches in the swamp brings them face to face with their own fears and vulnerabilities. As night falls, Gordie entertains them with a wild story about a character named Lardass Hogan, whose tale of revenge provokes laughter and temporary distraction from their larger concerns.
The next day, Ace's gang learns of their mission and pursues them. As they finally discover Ray's body, tension escalates with Ace demanding to take charge. Gordie's courage shines when he fires the gun, compelling Ace's gang to retreat. They collectively decide that they will not seek recognition for the gruesome find, opting for anonymity instead.
Ultimately, as Gordie reflects on their harrowing adventure, he narrates the fates of his friends. While Vern becomes a family man and Teddy bounces between jobs, Chris manages to pursue law yet meets a tragic end, echoing the very newspaper headline that sparked Gordie's memories. In closing, Gordie, now a writer, resumes his life by heading out with his son and a friend, eager to share joy. The narrative captures not merely the innocence of childhood but the profound impacts of friendship, loss, and the bittersweet passage into adulthood.
