Deskripsi：In 1994, three employees of the Yujiang Pharmaceutical Factory were brutally murdered on a typhoon night. Suspicion pointed directly to the factory’s leadership—Xu Chengliang, Duan Zhigang, and Du Bin—but due to insufficient evidence, the case was shelved, becoming a lifelong regret for veteran detective Shi Guangming. Fifteen years later, Su Ran, a descendant of one of the victims, returns to Yujiang with her husband Zhao Lun under the guise of journalists. Exploiting a counterfeit-drug scandal at the pharmaceutical factory, they draw close to Xu Chengliang and the others, carefully setting the stage for revenge. Su Ran first exposes Du Bin’s involvement in producing and selling fake drugs, only for Du Bin to be silenced soon after. She then provokes internal conflict by revealing an illicit affair between Duan Zhigang and Xu Chengliang’s wife, leading to Duan’s mysterious death. As a string of murders unfolds, Shi Guangming steps in to lead the investigation, and the situation rapidly escalates. Ultimately, through Su Ran’s intricate schemes, the hidden villains meet brutal ends, none escaping their fate. Yet Su Ran herself cannot evade destiny or the law. Having fulfilled her long-awaited mission, she discovers that its end brings betrayal among allies, separation from loved ones, and the shattering realization that even the father she never doubted was nothing more than an illusion.
