In the sleepy seaside town of Southport, a once‑carefree summer now hangs over the shoreline like a lingering fog. Four close‑knit friends return to the place they once thought invincible, each carrying the weight of a secret that has never truly been buried. When an anonymous, chilling note arrives proclaiming, “I know what you did last summer,” the ordinary rhythm of beach life is shattered, and a palpable sense of dread settles over the familiar boardwalk, the lingering heat of July, and the quiet lull of the ocean.

Julie James arrives back from college, finding herself torn between the longing for the carefree days of youth and the uneasy tension that now defines her friendships. Ray Bronson, who has drifted into a solitary life as a fisherman, is the quiet anchor in the group, his steady demeanor masking a restless unease. Helen Shivers, radiant and ambitious, clings to the promise of a bright future, yet the echo of past missteps lingers in her eyes. Barry Cox balances a carefree swagger with an undercurrent of anxiety, trying to keep the group’s fragile cohesion intact.

The town itself becomes a character, its sun‑drenched beaches and neon‑lit boardwalks juxtaposed against an unsettling undercurrent that suggests something far darker lurks beneath the surface. The tone blends nostalgic summer vibes with a looming, almost predatory menace, hinting at a relentless figure who knows their secret and is determined to expose it. As the friends grapple with their intertwined histories, the atmosphere tightens, promising a battle between buried guilt and the unforgiving present.

With each passing day the tension mounts, and the simple act of returning home transforms into a tense game of cat‑and‑mouse. The film teases the edge of terror without revealing the specifics, inviting viewers to wonder who — or what — is watching from the shadows, and whether the past can ever truly stay hidden.
