When a torrential storm strikes Yunling, Shen He, a young woman who gathers wild mountain produce, uses her years of wilderness experience to predict a landslide. She leads tourists to safety and risks her life to rescue Shen Lan, the manager of a rural guesthouse, and Shen Wanning. This brings to light a mystery surrounding their identities and a devastating flash flood twenty years ago. As a bronze bell, a baby swaddle, an identification plaque, and a series of genetic tests gradually reveal the truth, Shen He is confirmed to be Shen Lan's long-lost granddaughter. Meanwhile, Shen Wanning, who grew up under a stolen identity, repeatedly obstructs the family reunion and plots against Shen He out of fear of losing her family ties and career.
