The Lee family harbored a secret and it was believed that was how they could survive for generation and prospered no matter what the circumstances. The family was the decendant of the nine tailed fox. Once a female family member reached puberty, she would undergo a ritual to determine if she carried the genes of the nine tailed fox. If she did, she would be 'married off' and never see her family again. Lee Myung Ok was the youngest daughter of the family and her curiosity led her to discover that the marriage was a farce whereas in actual fact, the 'bride' was being sacrificed and killed so the family patriarch could prolong his life feasting on the liver of the nine tailed fox. When her only sister was killed in such manner, Myung Ok unleashed her fury and turned into a nine tailed fox herself to seek revenge. Is this the end of the family?
