Luna Sterling, chairman of Apex Holdings, the most powerful woman in Manhattan, received the news that her son Damon was seriously injured in a car accident at a shooting range. After arriving at the hospital, the doctor told his son that he might be paralyzed for life. Luna, distraught, vowed to find the perpetrator and take revenge. When negotiating with the perpetrator's mother, Nina, the other party was arrogant and domineering and took out a black card in an attempt to settle the matter with money. Luna was shocked to find that the card was actually the card she gave to her husband, Julian. The perpetrator was her husband's illegitimate daughter, and the woman in front of her was her husband's mistress. Luna is completely blackened, and a revenge storm of the chaebol mother sweeps across Manhattan.
