Song Ying, a single mother, raised three exceptional sons on her own: Lu Yunchen, a publicly listed company's president; Lu Jingyu, a boxing champion; and Lu Qinian, a top movie star. Uninterested in a life of luxury, she hides her identity and takes a job at her own family's restaurant. However, when the cleaner Li Juan mistakes her for Lu's mother because of a luxury car, a series of misunderstandings begins. A face-blind assistant, the snobbish manager Chen Yan, and others repeatedly mistake and humiliate Song Ying. Sun Yu also mistakes Li Juan for someone else and makes things difficult for Song Ying. Patiently enduring their behavior, Song Ying witnesses how people fawn over the powerful and look down on the less fortunate. Along the way, she reunites with her first love, Bai Yanfeng. At a Lu family banquet, her three sons publicly reveal the truth. The impostor Li Juan, the mean-spirited Chen Yan, and the others suffer the consequences of their actions. Song Ying approves of kind-hearted Sun Yi, an illegitimate daughter of the Sun family, as her eldest son's wife. In the end, Song Ying reunites with her first love, and the whole family finds happiness.
