After receiving the shocking news of her brother's sudden death, Carol and her companion travel to England to stay at the house of her mysterious sister-in-law. But there, strange, hair-raising evidence of occult practice catch nervous Carol's attention, and before long, she finds herself up against unspeakable, pure horror. Now, the black coven demands blood, sacrifice, and purification through torture and substance use. Is there an escape from the lair of satanic worship and the hideous sexual rituals of the devil?
