For two years, programmer Lin Cheng voluntarily helped single mother Zhou Man pick up and drop off her child. But on a stormy night, when he was just five minutes late, Zhou Man, a parenting blogger, falsely accused him of kidnapping. She had been using Lin Cheng as material for her posts all along, fabricating negative stories to attract traffic. As a result, Lin Cheng was publicly disgraced, lost his job, and became the target of online harassment. Driven into a desperate corner, Lin Cheng joins forces with a lawyer and uses his technical skills to gather evidence, forming an alliance with several other victims. A crucial audio recording is exposed, gradually revealing the truth behind the smear campaign. Zhou Man takes a reckless gamble by staging a fake kidnapping, but she is caught red-handed and ultimately sentenced to ten years in prison.
