On He Yunchun's resume, the words "driving screws" are like a curse - no factory is willing to take in this seemingly ordinary young man, just because he is the "sweeping monk" of the labor market: rogue intermediaries dare to withhold wages, and he can uncover evidence of tax evasion; unscrupulous bosses dare to squeeze working hours, and he can unite with workers to overturn the entire management system. No one knew that this "troublemaker" who was rejected by the factory just wanted to find a stable job. The story begins when he first steps into the "Shenghua Electronics Factory". The dormitory here is full of crouching tigers, hidden dragons: the "glasses guy" who can use legal provisions to cry against the foreman, the "old ghost" who can repair imported machines with his bare hands, and the "Myna" who uses his eloquence to resolve group fights... All of them are talented and speak well. He Yunchun originally wanted to live a low-key life, but unexpectedly, the exploitation of the gangster agency and the greed of the boss followed one after another. He was forced to show his true colors as a "nemesis" and lead a group of "marginal people" to set off a battle about dignity and fairness in the whirlpool of assembly lines and interests.
