In the summer of 1997, Xu Yunling, a young man, made a big mistake and was forced to leave his hometown in order to save his sick mother. He left his childhood sweetheart Jiang to say "I will come back when the clouds clear", but he did not know that she was pregnant.
Twenty-three years later, Xu Yunling, who was already a well-known architect, returned to Zhuxi Village with the "Rural Revitalization Demonstration Site" planning plan. What he faced was an internet celebrity B&B that he had to demolish - and the owner was Jiang Chichi, whom he had never forgotten in his life.
She is a country doctor, a single mother, and a stubborn woman who grew up guarding the old house and its secrets. He is a planning expert, a middle-aged man in a troubled marriage, and a wanderer returning home with deep guilt.
When the "future countryside" in his drawings encounters the "life scene" rooted in the land, and when the belated truth is revealed layer by layer in the mountain fog, they must answer: Is what we want to repair a dilapidated old house, or a broken time? Is what we are about to welcome a feast of capital or a return of people's hearts?
The clouds and mist on the ridge linger, like a sentence that has been asked for half a lifetime. And the answer is hidden in every tile, every medicine, and every inch of land they have run on together.
