Eight strangers from different worlds each receive a mysterious black envelope promising them their deepest desire. When they all arrive at a remote estate called Blackthorne Manor, they quickly realize they’ve been trapped with no way out and no explanation for why they were chosen. Among them is Y/N, who received the same invitation and stepped into the manor just like everyone else curious, unsure, and hoping for answers. But as the house begins to shift reality, expose secrets, and force them into impossible situations, it becomes clear this is not random. Blackthorne Manor reacts differently around Y/N, as if it recognizes them in a way it doesn’t with the others. Tension rises as trust breaks, alliances form and fall apart, and the group struggles to survive the manor’s psychological traps. With no escape and time running out, Y/N and the others must uncover the truth behind the invitation before the manor consumes them and before they turn on each other first.
