In a secluded monastery, where prayers whisper like breaths and walls exhale secrets, the nuns awaken to a horrifying scene... An inverted corpse, black blood staining the walls, and a demonic symbol proclaiming the beginning of a nightmare with no escape. Amid the shadows of fear and the distant tolling of bells, the abbess realizes that evil has breached the gates, and that Christ will not protect them this time. Between oppressive silence and creeping darkness, a terrifying journey begins-to uncover the betrayal that has awoken from its slumber... Who commands this horror? And can salvation find its way through the dark?
