In a mansion on the outskirts of Seoul lives one of the richest families in South Korea. Patriarch Yoon is the president of a multinational conglomerate, but his wife Madame Baek really holds all of the power. Her personal secretary Young-Jak, a handsome young man newly introduced to the world of wealth and influence, deals with the family's immoral - and frequently illegal - activities while he awaits his own opportunity to make it rich. When Madame Baek catches her husband having an affair and exacts her revenge by seducing Young-Jak, a torrid series of intra-familial deceptions ensues.
