An urban light comedy with "shuangwen" and "counter-attack" elements. 52-year-old retired female worker Ye Cuifen, in order to escape the exploitation of her children, enters a prestigious senior citizens' university, studying while earning money for her retirement. Feisty and fond of fighting against injustice, she offends Situ Yao, the hot-tempered retired chairman and core figure of the school's "F4", due to a conflict. In the subsequent "hit list" incident, Ye Cuifen is isolated by the entire school, but with her stubbornness and capability, she instead attracts the attention of Situ Yao, Gu Yuanshan (a former pianist), Murong Heng (a rich second generation), and others.
