The Other Child

Math genius Emma Payne gave birth to fraternal twins during an exam. The boy, Andy Winston, was stolen by Joyce and sold to the Winston family to avert a family disaster. Six years later, Emma joined Winston Group as a cleaner. Her daughter, Cathy Payne, had extraordinary mathematical talent, which caught Fred Winston's attention, earning her a qualification for an international competition. During the contest, Dona Shawn conspired with Joyce to frame Cathy for cheating, and humiliated Cathy and Emma. Fred intervened in time to clear their names and invited them to tutor Andy. Through daily interactions, Fred noticed remarkable similarities between Cathy and himself. So, he carried out an investigation and found that both Cathy and Andy were his biological children, while Dona had stolen Emma's identity years earlier. Ultimately, Dona's conspiracy was exposed. Fred reunited with Emma, and Andy returned to his birth mother, completing their family.
