Joseon Attorney: A Morality

Han-soo settles in Hanyang and opens an attorney's office. Being notorious for his rude attitude, he gets no customers for a long while. One day, a plum wine seller asks him to file a lawsuit against the leader of the biggest guild in Joseon, and the magistrate holds a court for this case.

Han-soo tricks Master Jang into standing as a witness for Pyo, a vicious criminal. He makes Master Jang make a false statement and get blamed for Pyo’s crime instead. Princess Yeon-joo decides to help Han-soo punish both Master Jang and Pyo. After seeing what Han-soo is capable of, she decides to use him for her future plans.

Lady Yeon, the wife of Commissioner Park, leaves her home to stay in Sowongak. It turns out that Commissioner Park abused her and intentionally killed her father to take all of his property. She wants to file a divorce suit against her husband, but it's difficult for a woman to do so in Joseon. Then Han-soo steps up to help her.
