Mari is told that she must work as an intern for Ji Hun before she is made an attorney.

Mari joins Jihun's defence. However, she cannot understand why Jihun is making a big deal out of a simple case. Jihun meets President Mo in prison for a covert chat. As Mari attempts to find Cheon Yeongbae's weakness, another victim shows up.

Mari and Sa Mujang advise Jihun to decline a request as the case is rather brutal. However, Jihun reluctantly agrees to defend the man who may have murdered his parents. Jihun's team must search for the truth.

Marie gets the feeling that all the people involved in the case are suspicious and that they are hiding something. Ji-hoon thinks that the painting he found in the mansion will be a big clue.
