Betrayal: The Hidden Criminal

Continuing from the ending of the TV series "The Unseen Sniper", Liang Xiaotang (played by Xie Tianhua) is convicted of murdering Su Xingbai (played by Huang Zongze) and sentenced to life imprisonment. While in prison, Liang Xiaotang meets university professor Huo Tianren (played by Wu Zhenyu), who appears gentle and unassuming but is capable of ensnaring the extremely dangerous 'Juchuan' (played by Lin Xue) using psychological traps. In fact, the professor is a high-IQ criminal psychologist who excels at cold reading, able to uncover others' psychological activities and secrets, thus controlling them silently. A mysterious woman (played by Wen Yongshan) visits Liang Xiaotang in prison; she belongs to a security bureau that is even higher than the police force. It turns out that Liang Xiaotang's imprisonment is a cover for her to take on an undercover role again. The day Su Xingbai was murdered, someone else was the actual perpetrator. The deputy director of the security bureau (played by Mai Changqing) suspects that the entire incident is related to a corrupt gang within the police force, and thus leverages Liang Xiaotang's imprisonment to conduct an investigation. Liang Xiaotang actively approaches his target in prison, the former drug investigation chief 'Daqie' (played by Dou Wenze). Just as he is about to make progress, he discovers that the professor is also manipulating 'Daqie' through psychological treatment, causing him to experience multiple mental breakdowns, ultimately leading to death hints directed at 'Daqie'. A tumultuous battle between indistinguishable allies and enemies, righteousness and evil, erupts under extremely unequal circumstances.
