After ten years, Jian Lin hones superb electrician skills. Returning to the city, he joins the steel mill, only to be mocked as a 'country bumpkin.' He is constantly undermined by Deputy Director Warren Wang. They don't know he can spot fatal flaws others can't fix; he handles accidents others won't touch. Facing credit-stealing, setups, and suppression, Jian Lin grips his wrench and fights his way back from the bottom as an apprentice.
