As the nation is rocked by a scandal involving 'national actor' Kang Eun-seok, who is accused of having an inappropriate sexual relationship with a high school girl, Yoo-jeong, Hyun-jin, a lawyer at L&J, struggles to prove Eun-seok’s guilt. By chance, Hyun-jin overhears a conversation about the Eun-seok – Yoo-jeong case at the home of her former lover, Jun-hyeok, and is taken aback to realize that the case is far bigger than she had imagined.

Jun-hyeok is found dead, and Yoo-jeong claims that she killed him. Hyun-jin finds it hard to believe, so she tries to find out the truth behind Ra-young and Shin-jae. Hyun-jin meets Seon-hwa, hoping she’d share some information about Jun-hyeok. Meanwhile, Ra-young comes home, only to be attacked by a mysterious man.

Seon-gyu takes DNA samples from Ra-young and Hyun-jin to compare them with the DNA found on an earring discovered at Jun-hyeok’s house. Ra-young pulls some strings so that the police don’t get their hands on Hyun-jin’s DNA. On the day of the crime scene reenactment, Yoo-jeong recants her statement.

Ra-young goes to see Min-seo at the restaurant she works at to convince her to get their help. Seon-gyu accuses Hyun-jin of visiting Jun-hyeok’s place on the day of his death. Min-seo decides to get help from L&J under one condition: To live with one of them. Min-seo starts working for L&J, and meets one of the clients from Connect.

Park Ju Hwan visits Ra Young at her office, leaving her shaken. He tells her that he’s going to reinvestigate his case from 20 years ago. Shin Jae finds out that Ju Hwan is part of the Connect scheme. Meanwhile, Attorney Kwon Jung Hyeon takes over LnJ as the new head in order to send Shin Jae to Haeil.

Hyun Jin shares the news with Seon Kyu that she’s pregnant. However, at the doctor’s appointment, Seon Kyu realizes that the baby might not be his. Jun Hyeok’s laptop gets recovered, and the voice recording of an interview with Yoo Jeong is revealed. Meanwhile, Lee Seon Hwa steals Jun Hyeok’s laptop for the corrupt cop.
