Wang Xiumei spent her life raising her ungrateful son, only to be kicked out of her home by her snobbish daughter-in-law. While wandering, she rescues Yuanyuan—the long-lost child of the city's wealthiest family—and raises him as her own for five years. When the billionaire family finds them, Xiumei is honored as a matriarch. But when her ungrateful son begs for her return to care for his own disrespectful child, a shocking kidnapping forces everyone to show their true colors. Xiumei must now choose between the blood that betrayed her and the billionaire legacy that honors her.
