In 1976, a modern machinist, Lu Zheng, transmigrates into a young man in rural Northwest China. Faced with an unwanted marriage and a biased family, he splits from his household and moves into a shabby hut with his wife Su Yufen. Using his mechanical skills, he starts by fixing tractors, joins the county auto repair factory, solves tough technical problems, wins a skill contest amid traps, and exposes the workshop director’s theft. He finally becomes head of the mobile maintenance team at the provincial transport company and heads to the provincial city with his wife for a new life.
