Luna Sterling, chairman of Apex Holdings and the most powerful woman in Manhattan, received news at the shooting range that her son Damon had been seriously injured in a car accident. When she rushed to the hospital, the doctors told her that her son might be paralyzed for life. Devastated, Luna vowed to find the responsible party and take revenge. During negotiations with the perpetrator's mother, Nina, who was arrogant and overbearing, she took out a black card in an attempt to bribe her. Luna was shocked to discover that the card was actually one she had given 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 completely turned dark, and a revenge storm from the mother of a financial empire swept through Manhattan.
