Retired German professor Chen Lan devoted half of his life to his family, but was wantonly despised by his son Jiang Wei, daughter-in-law Liu Min, and granddaughter Jiang Yue who studied abroad. At the family dinner, Jiang Yue insulted her in German. Chen Lan retorted fluently in German and left home decisively. She used her assets and connections to fight back, repossessing the property, freezing funds, revoking Jiang Yue's scholarship, and ruining Jiang Wei's cooperation project with another cross-border phone call. After the three people fell into despair, they resorted to misfortune to gain sympathy. When the truth was revealed, public opinion reversed. Liu Min went insane and Jiang Wei lived in poverty. Chen Lan took the repentant Jiang Yue back to China with a soft heart, and guided her to become independent by translating "Faust". She returned to academia and enjoyed a dignified old age.
