70-year-old Zhou Guilan suddenly reverts to her 20-year-old self and accidentally discovers her introverted granddaughter Xiaotang has been secretly writing songs, dreaming of becoming an idol but hiding it due to low self-esteem. To help Xiaotang chase her dream, Guilan—an old soul in a young body—disguises herself as Xiaotang's trainee roommate. She uses her "vintage wisdom" from her cultural troupe days to teach Xiaotang dancing, stand up to anti-fans, and even goes viral unexpectedly with her retro fashion. But just as they're on the brink of stardom, Guilan's body starts a "countdown"—if she can't find the "key to aging back" within 30 days, she'll stay 20 forever, unable to watch Xiaotang grow up. Caught between her granddaughter's dream and her own "deadline," what choice will Guilan make?
