A group of five college friends gathers for a reunion at a castle in Piemonte, Italy. According to local lore, the castle’s queen, Johanna of Anjou, was held responsible for a devastating drought and famine. Before being executed by the villagers, she cast a curse in her journal and took her own life. Captivated by this legend, the friends, in a drunken state, decide to explore the off-limits room where Johanna met her end. Inside, they discover her journal. This act awakens Johanna’s spirit, unleashing her terrifying desire for vengeance.
