The DefectsEpisode 6

Synopsis: Kim Se Hui is the chief director of a large hospital and the operator of a charity foundation. She is a highly respected doctor, but, unknown publicly, she is also the head of an illegal adoption organization that is run by Jung Hyeon. Kim Se Hui holds a twisted belief that only superior genes should survive. In the case of a child that is adopted through their illegal operation and does not meet the adoptive parents' expectations, Kim Se Hui's group provides a free refund for a certain period of time. When a child is returned by the adoptive parents, Kim Se Hui's organization kills the child to destroy evidence of their crime. Kim A Hyeon was one of the refunded children, but Kim A Hyeon dramatically survived. Now, she is the leader and a spiritual supporter of the survived children. She goes up against Kim Se Hui for survival and revenge.
