In a post‑apocalyptic world devastated by a plant‑based virus that transforms humans into resilient, zombie‑like hybrids, Ethan—a young man plagued by severe headaches and memory loss—clings to the hope of reuniting with his missing girlfriend, Emma.

During his journey, Ethan ventures away from the relative safety of the farm, including a trip to the abandoned cabin where he finds only a frightened woman and her teenage son instead of Emma.

As fragments of his lost memories begin to return, Ethan gradually uncovers a harrowing truth: he is already infected by the virus, slowly morphing into one of the undead.

"[9] Film critic Mel Valentin of Screen Anarchy commented: "While Die Alone experiences a slow midsection, it regains momentum with the arrival of home invaders and a religious family led by Kai (Frank Grillo).
