Lin Yue, a parcel-sorting worker, unexpectedly wins a grand cash prize of 680,000 yuan. When the news spreads, his team leader, Ma Weiguo, and several longtime coworkers, who have always exploited him, become consumed with envy. Pretending to celebrate his good fortune, they pressure Lin Yue into treating everyone to a meal. Behind his back, they secretly change the venue to the upscale Xuyuan Club. While Lin Yue is deliberately sent away, they feast lavishly and empty the gift shop's display cabinets, leaving behind an outrageous bill of 380,000 yuan and trying to force him to pay. Having already seen through their trap, Lin Yue calmly gathers evidence and carefully turns the tables on them. With undeniable proof, he delivers a stunning counterattack, making his greedy coworkers suffer the consequences of their own actions and exposing the true faces of workplace parasites as he turns his life around.
