After devoting half her life to hard work, Zhou Guifen is abandoned by her son at a highway service area during a National Day trip. Thirteen years of sacrifice and 470,000 yuan in financial support cannot even earn her a seat. At last, she realizes that loving her children does not mean losing herself. She sells the property in her name and sets off on a journey of long-term travel, rediscovering her dignity through calligraphy and exploring new places. After his marriage falls apart and his career hits rock bottom, her son Zhou Qiang starts over, going from food delivery rider to night-school electrician, learning responsibility and independence. Mother and son gradually move from estrangement toward reconciliation.
