[Genius profiler × Detective Captain Leng Sa × Gentle and protective senior sister]
[Double strong + criminal investigation suspense + triangle pull + ultimate redemption]
Genius profiler Su Qinghan can see through all criminals, but not his own heart.
She walked into the police force with a secret and became Xia Nanqi's sharpest knife and forensic doctor Xu Ying'an's deepest suspicion.
When the unresolved case is solved with the suspect committing suicide, when all the evidence points to Su Qinghan——
Xia Nanqi is struggling between duty and selfishness, and Xu Ying'an is wandering between truth and protection.
And the gentle senior sister Zhao Jingya who always leaves a light for her late at night is weaving a gentle cage with sweet traps.
"Sister Nanqi, do you want to interrogate me too?"
"Qinghan, come to me, no one can hurt you."
When trust becomes a bet, the truth becomes a trap. At the boundary between sin and redemption, whose redemption will she be, and whose prisoner will she become?
