Shao Feng, a driving instructor at a driving school in the northern suburbs, quotes his cousin a family rate of 6,800 yuan. His second aunt thinks it's too expensive and turns to Speedy Driving School, which advertises an all-inclusive, guaranteed-pass package for 4,500 yuan. But registration fees, guaranteed-pass courses, and retake fees keep piling up. His cousin lies about failing the test, then crashes a vehicle during practice without a passenger-side brake, costing the family a van worth 186,000 yuan. Armed with an itemized bill and a strict rule that students must pass three mock tests before being registered for the real exam, Shao Feng secures group training for 40 employees of Hengtong, winning back his reputation and business through genuine skill. In the end, his cousin walks into Shao Feng's large-class training session on his own. Not a single mark is left on the mirrors, and everything starts from scratch.
