After retiring upon completing a national classified project, Sharon Lee takes charge of all household chores for her family, uses her 50,000-yuan retirement pension to help her son pay off the auto loan and mortgage loan, and waits on the family like a nanny without complaint. However, only because she dyed her hair black for a family portrait, which made dinner half an hour late, she was berated, insulted and even kicked out of the house by the whole family. Sharon finally comes to her senses and leaves, takes back her retirement pension and stops paying the mortgage loan. The family only starts to regret their actions then, but it is already too late.
