Zhou Lan, a forty-six-year-old shopping mall cleaner, saves up money to sign up for a ninety-nine yuan one-day tour, embarking on a journey full of expectations with her colleague He Ying. Unexpectedly, as soon as the bus arrives at the shopping center, tour guide Xu Tong puts forward a consumption requirement of eight hundred yuan per family, and even prepares to adjust the scenic spot tour time. Zhou Lan takes out the registration agreement, insisting on voluntary shopping and itinerary transparency. Afterwards, shopping time is extended, lunch is upgraded with extra fees, and issues such as seat arrangements and photography projects arise one after another. Faced with various temporary changes, Zhou Lan always communicates rationally, and driver Cao Cheng also explains the actual arrangements according to dispatch records. He Ying gradually learns to independently judge consumption needs, while Xu Tong begins to change her service approach.
