In 2021, five friends arrive at a remote, run-down cabin in Tennessee to relive the nostalgia of 1981, only to discover that the isolated house hides a supernatural threat. As the night unfolds, a series of bizarre encounters turns their nostalgic getaway into a chaotic horror experience, while references to the music, cinema, and pop culture of 1981 gradually take over the story. Vincent Cassel ultimately becomes the last survivor, confronting the undead and transforming the cabin into a surreal tribute to the year, blending horror, dark comedy, music, and 1981 nostalgia before ending on an ominous cliffhanger.
