Following the death of Lord Ashworth, thirteen heirs are summoned to a remote ancestral castle to hear the reading of his will. What begins as a contest for a vast inheritance quickly becomes a lethal ordeal when the heirs learn that each must spend a night alone within the castle to claim their share. The estate is bound to a centuries-old legacy of violence, ritual, and a hidden treasure tied to a sinister family tradition.
As rivalries ignite, alliances fracture, and greed overtakes reason, the castle reveals itself as more than a decaying monument. It is an active force, steeped in bloodshed and secrets, driving the heirs toward paranoia, betrayal, and murder. Seraphina, one of the central contenders, uncovers evidence that the true inheritance is not wealth but a cycle of corruption embedded in the Ashworth lineage.
While older heirs destroy one another through ambition and treachery, the youngest, Defunta, observes silently from the margins. Long dismissed as harmless, she emerges as the embodiment of the family's darkest legacy. As the night unfolds and bodies fall, it becomes clear that the castle does not reward strength or intelligence, only ruthless adaptation. The gathering is not a test of worthiness but a mechanism of selection, ensuring that the legacy of violence continues through its most capable heir.
