S01E01 I Am Innocent
As a teen, prosecutor Hwang Si-mok received surgical treatment for his abnormally developed brain, but the procedure left behind serious side effects.
New pieces of evidence only increase the list of possible suspects. In the midst of the confusion, a few begin to question Si-mok's innocence.
Hwang Shi Mok underwent brain surgery as a child to curb his violent temper, which left him devoid of emotions. Hwang becomes a prosecutor known for his piercing intelligence and logic, but he is ostracized because he lacks empathy and social skills. He is also one of only a handful of upright prosecutors who have refused to take bribes. One day, he encounters a stabbing victim while investigating corruption. He meets Lieutenant Han Yeo Jin at the crime scene. They join forces to root out corruption at the prosecutors’ office and solve a serial murder case.
