During her driving lessons at a driving school, Lin Wan encounters multiple unreasonable treatments from her instructor, Coach Zhou, who defaults on advanced money, maliciously demands compensation using old vehicle damages, privately deducts training hours, and even colludes with management to sweep things under the rug and exert pressure. Resolute in character, she consistently adheres to her principles, using preserved chat logs, photos, and other evidence to rationally defend her rights. Step by step, she clarifies the facts and exposes the violations, ultimately not only reclaiming her own money but also helping other trainees defend their legitimate rights and interests. The relevant violators face corresponding penalties, and she successfully passes her driving test.
