Down-on-his-luck bus driver Lao Li turns his fortunes around with the support of Wang Qiang and a group of fellow workers. But once he becomes wealthy, he looks down on hardworking laborers, considering them uncouth. He repeatedly raises his fares and refuses to take them for no reason, determined to focus exclusively on high-end corporate team-building business. Unexpectedly, his true character is exposed, and he loses all his contracts. Unable to repay the loans he took out to purchase vehicles, he takes a dangerous gamble by operating an illegal taxi service and gets fined. Meanwhile, the honest and hardworking Lao Wu stays true to his principles and builds a successful fleet through his good reputation, proving that integrity and trustworthiness are the true foundations of lasting success.
