On a rainy night, an anonymous package was delivered to the door of Su Jin, a professor of criminal psychology. Inside was a photo imitating the scene of her sister's tragedy three years ago. The only postscript was: "The game begins." Su Jin's world collapsed again. Three years ago, she failed to profile her sister's murderer, and her career and heart collapsed at the same time. Now, she is forced to reunite with her old partner and current head of the special case team, Lu Yuan, and return to the dark edge she swore she would never set foot on.
New victims appear one after another. The murderer's techniques are precise and cruel, with a strong sense of ritual, and each time he delivers twisted information to Su Jin. Su Jin's profiling ability, which she was proud of, repeatedly failed when facing this "web-weaver", as if the other party knew every blind spot of her thinking. What frightens her even more is that the secret thread of all the evidence leads back to her sister Shen Qingyin.
During the investigation, a top-secret psychological experiment called "Spider Web Project" was gradually exposed. The childhood of Su Jin and her sister was actually a designed observation. Her memory begins to loosen, and the truth about that night three years ago becomes confusing. And when she finally came face to face with the "Web Weaver", what she saw was a face that had died three years ago.
Is my sister really still alive? Or has he already fallen into madness? In the center of a cobweb intertwined with trust and betrayal, memory and lies, Su Jin must complete the ultimate profile of her past - even if the answer will burn up the little life she has left.
