Bizarre things happen when a third-rate lawyer coincidentally takes charge of a murder case. It's a record of battles confronted by a lower-middle-class lawyer who must serve eviler than the villains. He needs to protect himself and his family and penalize the bad guys in a world of conspiracies and overpowering greed. Park Chang Ho—an unsuccessful lawyer—has a win percentage of only 10 percent. Those around him call him a big mouth: for talking grandiosely but showing no substance. He is so bad off that he can’t afford to pay the monthly rent for his office nor pay his office manager, who is also his father-in-law, on time. Go Mi Ho is Park Chang Ho’s wife: the person who made him a lawyer. During her college days, she was graceful and reserved, but now, she is bold and foul-mouthed.
