At first I thought that this drama was about a corrupt doctor being sent to prison and doing stuff but it turned out it was a revenge story of a doctor who unexpectedly got caught into a twisted plot and got sent to prison for a crime that he didn't commit. And while Na Ije strive to get his revenge he ended up unraveling the conspiracy between a big corporation involved in healthcare, the prison as well as the political scene.

Namgoong Min was really great at portraying the main character Na Ije, and Ilike the fact that there are scenes where he had to use sign language as Na's mother was deaf. And this was a very interesting twist in dramas involving doctors where the doctor was the one taking revenge.
