Wang Qiang, workshop manager of Hongyuan Machinery Factory, is jealous of talent and has long suppressed technical expert Liu Jianguo. Unable to bear the harassment, Liu Jianguo chooses to resign, having previously planted a protective lock in the underlying program of the equipment. Wang Qiang operates the core equipment without authorization, causing a major breakdown. The company receives a lawyer's letter, facing three million in breach-of-contract penalties, and the tens of millions worth of equipment is on the verge of being scrapped. General Manager Zhao spares no expense to invite experts, only to learn that forced decryption will directly burn down the equipment, leaving him no choice but to turn to Liu Jianguo for help. General Manager Zhao offers a high salary and equity incentives, which are coldly refused by Liu Jianguo. Having shaken off the vexing troubles of the old company, Liu Jianguo secures a generous compensation at his new workplace, enjoying a leisurely and stable life with his beloved, and past grievances can no longer disturb him.
