During the May Day holiday, hotel owner Lin Yao reserves 30 rooms for Zhang Hao, a loyal customer who has worked with her for ten years. Her all-inclusive price of 500 yuan per person covers three meals, attraction tickets, and transportation—a fair price she has steadfastly maintained without raising it. But when Zhang Hao sees that individual guests pay only 400 yuan for a room, he accuses Lin Yao of taking advantage of loyal customers. Refusing to listen to her explanation, he slaps her and forcibly cancels the booking. Lin Yao doesn't argue and instead sells the vacant rooms to a hundred-member senior citizens' tour group urgently seeking accommodation. The elderly guests' genuine positive reviews send the hotel's reputation soaring, while Zhang Hao and his employees encounter rejection everywhere. After staying in shabby guesthouses and even sleeping under an overpass, Zhang Hao causes a disturbance at an industry conference, gets detained, loses his job, and is blacklisted by the industry.
