My Lawyer Mr. Jo

Jo Deul Ho was a promising prosecutor who was married to the giant's daughter in the law. He was the most renowned prosecutor in Seocho District. One day, he witnesses an intolerable corruption, and he went against it. It turns out the world was not taking the hand of justice. In a moment, he becomes a criminal and falls on the street. After three years of wandering on the street, Jo Deul Ho is back in the business as a lawyer.

Ex prosecutor Deul Ho who is now a lawyer, takes the case that happened three years ago which is also related to his scandal when he was the prosecutor. Together with Eun Jo, the co-counsel, it seems like Deul Ho is taking the groove being on the other side of the court. Meanwhile, Jeong Geun Mo, the chairman of Daehwa corporation who was responsible for the downfall of Deul Ho three years ago, is taking another move with Woo Jang to take Deul Ho away from the case.

Deul Ho gets a new piece of evidence from the ex-detective, who worked on the case three years ago together with him. The ex-detective tells Deul Ho that by possessing this evidence, the life of Deul Ho may be in danger. Meanwhile, Byeon Ji Sik decides to stop claiming his innocence after knowing that his son might get influenced throughout the trial.

Deul Ho finds a witness who saw the car accident that killed the guy who is being the victim of the murder case of Byeong Ji Sik. Byeong Ji Sik was accused of murdering his fellow man and burning down the building together with the body. However, it turns out that another person is responsible for the victim's death by hitting the victim with his car. Byeong Ji Sik went back to his home after clearing his charge. Meanwhile, Deul Ho comes across with his second case as a lawyer.

The poor tenants in the market are endangered from being evicted due to the reconstruction of the community. The landlord, Micheal Jeong, is the son of the chairman of Daehwa corporation. Deul Ho decides to help the pork bone stew owner he refers to as 'mom.' Meanwhile, attorney Eun Jo as a lawyer of the Geum San law firm, becomes the deputy of Daehwa corporation.

Fellow tenants of the Pork Bone Stew Place owner appear on the eviction hearing to testify about the landlord's illegal interference with their business. Deul Ho accuses the landlord of his aggressive tactics to drive the tenants away from the market and led the landlord to drop the case. Deul Ho visits Michael Jeong after the trial to deliver him one last warning to turn himself in for the arson and murder he committed three years ago.
