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.
Enraged by what the police did to Park Kyung-wan, Yeo-jin tries to confront her superior but is stopped by Si-mok, who warns her of the consequences.
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.
