Chen Yuan, a 38-year-old freight driver, was driven to collapse by debt and family pressure, and chose to end everything by the river. The moment he jumped, he accidentally exchanged souls with a strange young girl playing in the river.
Standing in someone else's young body, he looked back at his own miserable life; the girl lived in the body of a middle-aged man and experienced firsthand the difficulties of an adult raising a family.
There is no ambiguous love, no cheating and counterattack. A wonderful exchange journey allowed him, who had been escaping for half his life, to finally let go of the idea of committing suicide, understand his responsibilities, reconcile with life, and finish the journey well.
