Steel Forest

A female corpse brings out new clues in the "8.17" unresolved case, and the old case is reopened. Criminal psychology professor Jiang Hansheng (played by Jing Boran) parachutes into the task force, which shocks criminal investigation policewoman Zhou Jin (played by Cai Wenjing). Her husband from a flash marriage was actually a provincial police officer, and the investigation is directed at her childhood sweetheart and first love Jiang Cheng (played by Qin Junjie). The three people who were trapped at the bottom of their lives due to a dusty old case are entangled again. Whether they can break through the many secrets and traps to find out the truth and heal their loved ones is the most difficult riddle of fate.
