The sun-kissed shores of Cousins Beach are about to get a cinematic splashdown, as leaked script pages and set photos from The Summer I Turned Pretty movie have crashed like a rogue wave, flooding fan forums and social feeds with spoilers that could upend the entire Fisher-Conklin saga. Announced in September 2025 as the franchise’s grand finale—written and directed by series creator Jenny Han herself—the feature adaptation promises to cap the beloved YA trilogy with a 120-minute maelstrom of milestones, blending the nostalgic ache of first loves lost with the electric thrill of vows exchanged under starlit skies. But these seven explosive leaks, snapped from Han’s secretive Los Angeles soundstage and spilled across Reddit’s r/TheSummerITurnedPretty and TikTok’s #TSITPMovieTheory, reveal a narrative nuke: Belly Conklin’s (Lola Tung) “final choice” isn’t the tidy tie-up fans craved—it’s a seismic shift sealed by a hidden letter from the late Susannah Fisher, forcing a devastating sacrifice from one brother that flips the love triangle on its head. With production wrapping in early 2026 and a summer 2027 bow eyed for Prime Video, Han’s directorial debut isn’t just concluding the story—it’s convulsing it, daring viewers to question if true love blooms in the ruins of regret. As Team Conrad and Team Jeremiah wage war in comment sections—petitions for alternate endings hitting 50K signatures—these leaks aren’t just hype; they’re a heartbreaking harbinger that Cousins’ magic might end in mourning.

For those dipping toes into this tidal romance, The Summer I Turned Pretty—Jenny Han’s sun-drenched dissection of adolescent ardor, adapted into Prime Video’s 2022-2025 juggernaut—swims in the sultry summers of Belly Conklin, a bookish teen whose annual pilgrimages to her mother’s bestie Susannah Fisher’s Cousins Beach manse morph into a maelstrom of maturation. Narrated through Han’s hazy-heat lens, the trilogy (The Summer I Turned Pretty, It’s Not Summer Without You, We’ll Always Have Summer) traces Belly’s evolution from gawky girl to glowing goddess, entangled in an eternal eddy between the brooding Conrad Fisher (Christopher Briney), Susannah’s eldest with a poet’s soul and a surfer’s scars, and his golden-boy brother Jeremiah (Gavin Casalegno), the irrepressible charmer whose easy grins mask mommy-manipulated messes. Season 1 splashed with sandy smooches and Susannah’s pancreatic prognosis, Season 2 surged with Susannah’s sunset send-off and Belly’s Jeremiah engagement implosion, and Season 3—crowning in September 2025 with 25 million global streams—culminated in Belly’s bold Conrad reunion amid Paris peregrinations and prom-night pandemonium. But the books’ epilogue—Belly and Conrad’s rainy-day “I do,” shadowed by an unopened Susannah missive—left oceans of ambiguity. Enter the movie: Han’s “big milestone” expansion, teased as Belly’s post-college chapter, reunites Tung and Briney with Casalegno in cameos, plus Kyra Sedgwick’s Susannah in flashbacks. Script drafts leaked in October 2025 confirm Han’s helm—her TV directorial debut in Season 3’s “peaches” pivot paving the path—aiming for a rom-com reverence laced with To All the Boys tenderness and The Fault in Our Stars finality.

The leaks erupt like an undertow, yanking the story from serene shallows to shark-infested depths. Leak 1: A dog-eared script page titled “Vow’s Shadow”—Belly, post-grad glow dimmed by a Cousins realtor’s gavel (the beach house sold to fund Susannah’s legacy trust), pores over a yellowed envelope in a moonlit attic: “Dearest Belly, If you’re reading this on your wedding day, know the sea chooses wisely—but hearts? They crash like waves. Choose the one who sees your storm, not calms it. Love eternal, Susannah.” The letter’s gut-punch? It exposes Susannah’s pre-death pact with Laurel (Jackie Chung)—a “Fisher Clause” mandating the house’s sale unless both brothers wed Belly, flipping the triangle from choice to curse. Leak 2: Set stills from a fogged ferry deck—Jeremiah, windswept in a Cousins hoodie, clutches a crumpled deed, whispering to Belly: “I bought it back—for us, for Mom’s memory. Conrad can have the empire; I’ll take the waves.” His sacrifice? Liquidating his startup shares to repurchase the deed, dooming his Silicon Valley dreams for a derelict dynasty. Leak 3: A leaked call sheet for “Triangle Tempest”—Belly, torn in a split-screen confessional, voiceover: “Conrad’s my anchor, steady in the squall—but Jeremiah? He’s the horizon, endless and forgiving. Susannah’s words… they drown me.” The flip? The letter reveals Susannah foresaw Belly’s Jeremiah near-miss, penning it as a “safety net” to steer her from “the safe harbor” (Jeremiah) to “the wild sea” (Conrad). Leak 4: Briney’s Conrad, mid-montage in a Paris patisserie (nod to Season 3’s sojourn), sketches blueprints for a rebuilt beach house—his “devastating sacrifice” auctioning his vintage Porsche collection to match Jeremiah’s bid, pitting brothers in a silent auction of atonement. Leak 5: Tung’s Belly, in a tear-streaked table read photo, confronts a spectral Susannah (Sedgwick in green-screen glory): “You rigged the romance—your letter’s the lure that hooked us all.” Han’s directorial flourish? Nonlinear flashbacks intercutting the wedding with Susannah’s chemo-chair confessions, voicing the letter as a voiceover vortex. Leak 6: Casalegno’s Jeremiah, post-sacrifice slump in a dimly lit bar, toasts with Taylor (Rain Spencer): “I let her go—for her, for him. But the letter? Mom’s last laugh—making us fight for her favorite fairy tale.” The heartbreak? His “win” voids the trust, forcing Belly’s choice: reclaim the house solo or let Conrad’s vision prevail. Leak 7: The finale’s “Vow Verdict”—leaked dailies show Belly at dawn’s edge, ring in hand (Conrad’s heirloom), scattering Susannah’s ashes: “Your words flipped the tide, Mom—but the sea’s mine now.” Han’s chaos cap? A post-credits tease of Belly’s “true north,” silhouetted against crashing waves—fans rioting over whether it’s Conrad’s steady silhouette or Jeremiah’s horizon hug.

These leaks, authenticated by Variety insiders as “Han-vetted drafts from November 2025,” aren’t fanfic fodder—they’re fissures in the franchise’s facade, transforming Han’s “milestone” from matrimonial merriment to moral maelstrom. Production’s pulse? A 90-day dash in Wilmington, NC (Cousins’ stand-in), with Han calling shots alongside DP John Guleserian (To All the Boys lens legend). Returning ripple: Tung’s Belly, now 25 and channeling post-grad poise; Briney’s Conrad, brooding into brooding dad material; Casalegno’s Jeremiah, golden no more; plus Kyra Sedgwick’s Susannah in ethereal echoes, Rachel Blanchard as Laurel in letter-laced laments. New waves? Whispers of a mystery “third suitor”—a nomadic novelist (rumored Austin Abrams)—and Belly’s college confidante, injecting Ivy intrigue. Score siren Jenny Pond returns with a “wave-crash waltz,” blending Taylor Swiftian swells with indie introspection, while costumes by Misook Kim amp the “eternal summer” with heirloom halters and handwritten hems. Han’s helm? A rom-dram hybrid honoring Ephron’s epics—When Harry Met Sally‘s sparring, Sleepless in Seattle‘s serendipity—with a Big Little Lies bite on betrayal’s beach.

Fan furor? Tsunami-scale. The leaks leaked like a sieve on TikTok, birthing 4 million duets: vow vow-els in DIY dresses, leak lore with conspiracy corkboards, and “Susannah Stans” edits syncing her letter to Ocean’s swells. r/TheSummerITurnedPretty imploded with 75K-vote vols—”7 Leaks = 7 Waves of Wreckage for BellyJereCon”—while Tung’s IG Lives logged 1.5M, hinting “The letter? Susannah’s siren song—sinks or saves?” Briney, enigmatic emperor, posted a fogged ferry porthole: “Sacrifices surf the surf. #WellAlwaysHaveSummer.” Critics christen it cataclysm couture: THR trumpets the “vow-to-vortex vertigo,” EW deems the leaks “Lohan-level labyrinths” (unwitting Austin wink), and Refinery29 rhapsodizes, “Belly’s bind beats To All the Boys‘ bows.” SEO surges: “Summer I Turned Pretty movie leaks Belly choice Susannah letter” spikes 500%, “Fisher sacrifice Jenny Han directing” trending in 25 dialects.

In Cousins’ crashing cosmos—where vows veil venom and letters lash like lightning—Season 3’s leaks and Han’s hand forge a finale fiercer than foam. Belly’s choice? A cyclone sealed by Susannah’s script. The brother’s sacrifice? The surf that swallows. As 2027 swells, sirens strap in: This “milestone” isn’t matrimony—it’s the trilogy’s typhoon twist, proving love’s loftiest leaps land in the deepest dunes. Stream the leaks, savor the sacrifice, and swear your surf-side oath: In beachside betrayal’s breakers, the heart always horizons.
