On a dark blue sea, on an uncharted, uninhabited island, the ugly nature of humanity is revealed. The island's owner, ‘Soh Myung,’ kidnaps women who have committed sins and imposes sexual punishments on them, satisfying his own desires. Is he a judge punishing sins, or a fallen man indulging in pleasure? Caught in this conflict, he binds more and more women, unleashing his desires. Through the intense emotional changes of the characters—past regrets, anger, pleasure, and more—this story questions the boundaries of ethics and morality.
