Chen Dapeng, an elite employee at a major tech company, returns to his hometown to rebuild his family's old house. Convinced that his internet mindset and digital management skills give him a decisive advantage over traditional rural construction methods, he publicly dismisses Uncle Lao Gan, an experienced construction foreman, to save 30,000 yuan in management fees and takes charge of the entire project himself. Once construction begins, a series of disasters strikes: neighbors cause disturbances and obstruct the work, a sand and gravel supplier delivers substandard materials, temporary workers deliberately slack off, a localized downpour destroys building materials, and workers make fraudulent safety claims. The contracts, data, and procedures he regards as absolute principles all collapse in the face of rural customs and personal relationships. Not only does the construction cost soar far beyond budget, but the ordeal also drives his father to the brink of collapse.
