When every victim in a string of serial cases appears in a place no one could have expected, only Shen Zhao, a former psychological profiler, can predict what comes next. The new team captain, Lin Yanqiu, doesn't believe in the supernatural, but has no choice but to rely on him to solve the case. The sister of a missing girl, a silent painter, a deputy bureau chief hiding the truth: everyone has clues concealed in the dark. When the predicted sequence overlaps with their memories, they discover that the killer isn't murdering people, but recreating the trial buried twenty years ago.
