This episode of Wrong Station presents a horror anthology centered on a cursed castle and its immortal servant, the Castellan. Three distinct travelers—a medieval peasant, a WWI deserter, and a modern backpacker—seek refuge, only to be hunted by the creature who awaits its master’s return. While the first two victims are brutally killed, the final protagonist survives by decapitating the monster, inadvertently triggering a supernatural transformation that reveals the true, terrifying nature of the castle’s master.
