Kevin and Soozi, a young couple deeply in love, set out on a romantic getaway to her secluded ancestral estate. What begins as a dream trip soon turns into a nightmare when Kevin uncovers a chilling truth hidden within the family’s walls. Soozi’s relatives belong to an ancient tantric cult that believes human sacrifice is the key to spiritual transcendence, and their chosen victims are individuals with the rare O-negative blood type. As Kevin realizes that his blood group made him a target from the very beginning, he discovers that Soozi’s affection may have been part of a sinister plan. Imprisoned and subjected to a gruesome ritual, Kevin must summon every ounce of courage to escape a house steeped in betrayal, bloodshed, and unspeakable terror.
