Tailor Zhou Hui accepts an old suit brought by Li Jing, intending to alter it for her ten-year-old boy Qin Zixuan to wear at his graduation ceremony. While altering the garment, she discovers a movie stub left by Qin Yuan inside the inner pocket, realizing the suit carries the family's past memories. Finding the outfit old-fashioned, Zixuan impulsively cuts and ruins the suit out of spite. Zhou Hui mends it once again and sews the ticket stub into a new pocket. As his mother recounts past stories about his father, Zixuan gradually understands the meaning of this old clothing. At the graduation ceremony, wearing his father's suit to tell his family's story, he finally embraces his longing and brings peace of mind to Li Jing.
