Many sophisticated and perfect crimes occurred in Lincheng one after another. The murderer destroyed all physical evidence and created the illusion of a secret room. Several cases reached a deadlock. Shen Wang, who has the ability to read microscopic minds, was specially hired by the city bureau as a criminal psychology consultant. She does not rely on traces at the scene, but only on micro-movements and emotional flaws that cannot be concealed, to see through the disguise and uncover the hidden evil.
Criminal investigation captain Lu Zheng believes in the supremacy of ironclad evidence and initially did not approve of this almost metaphysical way of solving cases. The two ran into each other in dangerous unit cases, from being wary of each other to trusting each other. They gradually discover that behind all the murders, there is a secret villain who is good at psychological planning, and the opponent specially sets many traps for Shen Wang's abilities. Working together, the two faced the abyss of people's hearts, fought against the darkness, defended justice, and gained a relationship of two-way redemption.
Purpose: Uphold justice, the flaws of human nature can never be completely covered up, and sin will eventually be judged.
