Office worker Su Xiaoxiao has been a loyal customer of the restaurant downstairs for years. She often leaves extra tips and even recommends the place to her colleagues. But after questioning a missing dish in her order, she becomes the target of the elderly restaurant owners' resentment and humiliation. The next day, they show up at her workplace with a lunchbox, spreading rumors and demanding 3,000 yuan in compensation. Her supervisor and colleagues accept bribes, join forces to make things difficult for her, and even steal her clients. Su Xiaoxiao gathers a complete set of evidence, including audio recordings, surveillance footage, and proof of food safety and fire safety violations at the restaurant. She simultaneously files real-name complaints with multiple authorities, successfully exposing the extortion scheme. The restaurant is forced to close, the bribed supervisor and colleagues are disciplined, and the owners are dealt with according to the law. With comprehensive evidence, she successfully defends her rights.
