Reborn back to 1988, Chen Yansheng carries the lingering memories of his past life and completely bids farewell to his humble and flattering past. Facing his cold wife Shen Zhiqiu and Zhao Jingchuan, who stole the fruits of his labor, he no longer bears humiliation and makes concessions. Relying on his solid mechanical skills, Chen Yansheng breaks free from the shackles of the Shen family and heads to the harsh conditions of the south city branch factory. He holds fast to his original aspirations, exposes conspiracies, takes root on the industrial frontline, proves himself through hard work, and walks out an upright life belonging to a technical worker in the tide of the times.
