Xu Wangyun went missing after a car accident en route to meet her husband Jiang Mingxiu. Rescued by Fang Qiang who claimed she was his wife, she spent 75 years caring for his son Fang Wenpeng. When Wenpeng got hired by Jiang's Siyun Group, the father-son duo tried selling their home to move city—nearly exposing the lie. After assaulting Xu, they fled, but her relentless pursuit caused her to miss Jiang who was searching for her. A dropped wallet containing their love token finally reunited the long-lost couple.
