Nineteen-year-old Lin Xiaoyou transmigrates into the body of 66-year-old Wang Guilan and becomes bound to a Life Comeback System. At the nursing home, she leads the elderly in breaking free from their repressed lives. She stands up to abusive caregivers, organizes social dancing, starts livestreaming, and holds anti-fraud activities. She takes the residents hair-dyeing, into escape rooms, and out dancing. She also uncovers a misunderstanding surrounding a first love from half a century ago and organizes matchmaking events for seniors. When an undercover instigator tries to sow discord and powerful business interests scheme against them, she repeatedly turns the tables with a complete chain of evidence. In the end, the residents go from being passive to taking the initiative, organizing real-life CS games and roaring through the streets on motorcycles. They prove that age is no prison and that they can take charge of their own golden years.
