After becoming a widow, Lin Suhua worked hard on her own for over twenty years, buying a house and a car for her son. Yet when she sat in the front passenger seat, her son dragged her out of the car, while her daughter-in-law falsely accused her of being overly attached to her son. Her son even demanded that she kneel and apologize. Heartbroken, she decided to take back everything she had given them and kicked them out. Her son then teamed up with his grandmother and girlfriend to spread rumors and launch an online harassment campaign against her, even causing her hotpot restaurant to be surrounded and attacked. When an employee named Xiao Tang protected her, a crescent-shaped birthmark was revealed. Following this clue, Lin Suhua discovered that years ago, her mother-in-law had switched her biological daughter with her husband's illegitimate son, Zhou Tao, in order to have a grandson. She gathered evidence, won the lawsuit, and reunited with her daughter. To her adopted son, who begged for forgiveness on his knees, she declared, "We're even now." At last, she began living for herself.
