An unexpected test result sets off a story that should never have happened. Qin Yujie is pure, upright, and fiercely devoted to her career. Unwilling to become a mere appendage to her wealthy husband, Gao Changshun, she often has to drink and dine with clients for work. This sparks suspicion and resentment from her father-in-law, her husband's aunt, and her husband, who begin to doubt whether the child Qin Yujie gave birth to is really part of the Gao family. Incredibly, when the grandfather takes a biological sample from his grandson to the hospital for a DNA test, the results show that the two are not related by blood. To throw Qin Yujie and her son out of the house, protect the reputation and career of the flourishing Gao Changshun, and ensure Qin Yujie doesn't take a single cent from the Gao family, Gao Changshun's father, aunt, and Gao himself scheme and carry out a series of despicable, underhanded deeds. Their actions reveal just how cruel human nature can be.
