Sheng'an Group Chairman Chen Lishan disguised himself as Chen Shan, entered a factory to work, and bumped into the management withholding wages, ruining food, and bullying fellow workers. He ate and lived together with the workers, solved difficulties anonymously, and secretly investigated the profit chain extending to the group headquarters. At the annual meeting, the villain was just about to drive him away in public when a shout of "Chairman Chen" stunned the whole audience. The boss revealed his identity, settled accounts with the wicked, and reclaimed justice for his fellow workers.
