Shen Yi is a portrait. When solving a crime, he can draw a criminal with the help of the voice of the suspect, the sense of bone and the description of words and phrases, and he can also restore the skull to the appearance before his death. It can be said that the role of the portrait painter has been deified. She is a genius simulated portrait painter in this play. When she first entered the police station, everyone didn't recognize him because they felt that only the words and phrases of the victim were enough.

Another case is the kidnapping case. At the beginning of this kidnapping case, all of them had no clue, and they were deceived by the criminal. Because she played the triangle by herself in the play, the criminal was very cunning and could change his face, so she deceived all the police at first. When describing the criminal, the preface was inconsistent, so Shen Yi never drew the criminal, but in the end, only he found out that there was no "Three" at all.

This drama has been well received since it was broadcast, and the plot is very compact. Just after one case was solved, another case appeared, and he also solved a case of cosmetic rape. At first, no one thought that the leader of this case was actually the victim Jiang Ge, who was able to draw it even when the criminal was wearing a mask. It can be said that she is like a god in this drama, and I feel that all cases need his portrait to be solved. This is also a criminal who made her feel very sorry. Because Jiang Ge was discriminated against by his professional appearance, he had to choose plastic surgery, but he finally fell into the clutches of plastic surgery doctors and threatened him with CDs. So Jiang Ge killed the plastic surgery doctors and made a perfect alibi, but in the end he couldn't escape Shen Yi's eyes. Although the criminal was smart, the crime was a fait accompli, so he was finally arrested.
