Jiang Yanqiu, a former profiler who was forced to put on a police uniform, triggered a panic among criminals in the city that night - because she knew the true face of 'Shadow Crow'. Interpol captain Lu Xiao was ordered to track her, forensic doctor Bai Zhi secretly handed over evidence in blood letters, and information trafficker Zhou Jin posted fatal coordinates on the dark web. But when the orphan Ah Qi put on her police badge, Lin Zhao's smile slowly appeared on the surveillance camera. She is not a hero, she is the fire that ignites hell. Every time she solves a case, someone dies because of the truth she uncovered with her own hands. The whole city's criminals were waiting for her to break down, and she was waiting for everyone to reveal their true face.
