Seven days before her wedding, an indecent video sends PR director Xu Zhi to the top of the trending list. Her fiancé puts the wedding on hold, and her company is the first to distance itself from her. Only her ex, Lu Chen, who is helping with the investigation, says after watching it, “It’s not that the fake is too convincing. It’s that someone knows you too well.” She must follow the trail through deepfake videos, trending-topic traffic, and the black market in identity samples to reclaim her name from the System.
