Wang Guiying, an elderly pregnant woman, accidentally conceived a child with Qiao Zhendong, the richest man, at a classmates' reunion. During childbirth, her best friend Liu Aihua swapped the baby and falsely claimed to be the biological mother. Five years later, the twin siblings Qiao Kaikai and Qiao Xinxin escaped from the wealthy family and accidentally met their down-and-out biological mother Wang Guiying, who was selling boxed meals. The cute kids acted as amazing matchmakers, helping their parents reconcile. In an attempt to seize the family fortune, Liu Aihua set up a scheme to extort money and even kidnapped her own biological child. Eventually, her crimes of drugging and swapping the babies were publicly exposed at the wedding scene. After going through hardships such as selling a kidney to save her child and being forced into marriage by villains, Wang Guiying finally joined hands with Qiao Zhendong to expose the conspiracy. Her advanced-age pregnancy ushered in a new life.
