Dokgo Young visits Choi Ja Hye to complain about what she said on her TV show. Choi Ja Hye has an opening party for her law firm. Kim Hak Bum is upset that only he didn’t get an invitation to the party. While Hak Bum, Joon Hee, and Tae Suk are having a party, Yum Mi Jung and Kang In Ho meet each other in secret.
Hak Bum, Joon Hee, Tae Suk, and In Ho gather together for dinner. Mi Jung suddenly visits them. In Ho gets angry as Mi Jung teases him in front of Na Ra. Young continues his attempts to meet Mi Jung, but he hears that she has not been seen for days. Meanwhile, her dead body is found in the middle of nowhere.
Young arrests In Ho as a suspect on the case of Mi Jung’s murder. He thinks In Ho is the murderer and investigates the case to look for evidence that points to him. Na Ra seeks for Ja Hye’s help after seeing In Ho get arrested, and Ja Hye tries to reveal the truth behind the case as In Ho’s attorney.
Ja Hye and Young continue their investigation. However, Ja Hye finds more evidence that proves In Ho’s innocence and starts to think that one of In Ho’s friends may be the real culprit. As Ja Hye continues her investigation, Tae Suk, Joon Hee, and Hak Bum all get nervous.
As Yum Mi Jung’s corpse is returned to Tae Suk, Hak Bum, and Joon Hee, they become suspicious about each other. Na Ra finds a picture of In Ho and his friends, and she realizes that they have known Mi Jung for a long time. Because of such events, Na Ra becomes angry and decides to join Ja Hye’s law firm as an attorney to reveal the truth.
Na Ra asks Joon Hee to help prove In Ho’s innocence. He tries to report about what happened with Mi Jung’s body to the police and calls Na Ra to say that In Ho will be proven innocent. However, Hak Bum and Tae Suk is trying whatever it takes to stop Joon Hee.
Tae Suk and Hak Bum push Joon Hee and his car off a cliff to conceal the truth about what happened. After doing so, Tae Suk and Hak Bum decide to create an alibi. Ja Hye and Young help each other out while investigating Joon Hee’s accident alongside with Mi Jung’s death. Meanwhile, Joon Hee’s body and car gets found.
Tae Suk tries to stop the police from running a DNA test on Joon Hee’s body. Young’s instincts tell him that the body may have been swapped, so he tries to make the DNA test happen no matter what. Meanwhile, several masked men attack Young.
Ja Hye and Na Ra find a clue leading to Seo Joon Hee’s whereabouts. Tae Suk eavesdrops on Young as he tells Joon Hee’s father about the DNA test results. Dong Bae and Young find the manufacturer of the badge Ja Hye gave him. Meanwhile, Tae Suk orders Hak Bum to sell the car they drove on the day they attempted to kill Joon Hee.
As Dong Bae disappears with the truth about the missing case of Seo Joon Hee, Dokgo Young becomes furious and chases after him. After some searching, Young finally catches up with Dong Bae, but he manages to escape again. Meanwhile, Tae Suk and Hak Bum put a tail on Young to find where Joon Hee is.
Ja Hye and Young meet each other at Sunshine Nursing Home. They are suspicious about each other but are able to check that Joon Hee is still alive and kept there. Hak Bum’s car dealer finds out about the video on his dash cam and tries to threaten him to get money. Meanwhile, another attempt to abduct Joon Hee is made.
Someone new visits Gangdong Precinct and looks into the murder case from Paju. Hak Bum asks for Tae Suk’s help to take care of his car dealer, Kim Byung Gi. Young finally manages to catch up with Dong Bae. After hearing what has happened to Dong Bae, Young visits Ja Hye to share what he found out.
After killing the car dealer, Tae Suk forges his own alibi and makes the investigation head for Hak Bum instead. Tae Suk uses this to threaten Hak Bum and make him do as he orders. A woman visits Young and says Byung Gi has disappeared. She suspects that it has something to do with In Ho’s case. Meanwhile, Byung Gi’s car has been found.
Young tries to ask Hak Bum if he knew anything about Byung Gi’s disappearance, but Hak Bum refuses to answer. However, Young finds a clue during his investigation elsewhere. Na Ra finds Kim Jung Soo, the surgeon at Daemyung Hospital, acting odd. Meanwhile, Ja Hye reveals a new suspect on In Ho’s first trial to reveal the truth of Yum Mi Jung’s murder.
Kim Jung Soo tells the court about what happened to Kim Soo Hyun 10 years ago. Due to the reasonable doubt in finding In Ho guilty, he gets acquitted. Hak Bum is not sure if Byung Gi is really dead or not, so he and Tae Suk go back to where they buried him. Meanwhile, Young starts to investigate Jung Soo as a suspect for the murder of Yum Mi Jung.
Young continues to investigate Jung Soo. In Ho, Hak Bum, and Tae Suk visit Joon Hee together and talk about what happened. As a suspicious video clip of Jung Soo leaving the Stellarium Villa in the middle of the night is found, Young gets surprised by an unexpected turn of events. Meanwhile, In Ho receives a USB from Byung Gi’s colleague.
Ja Hye delivers a Demand for Fulfillment of Obligation as Kim Byung Gi’s legal representative to Tae Suk. Young finds a strange drawing in Kim Jung Soo’s house and starts to look into what it leads to. Meanwhile, In Ho receives a text message from Byung Gi to meet, and to pay him two million dollars.
Young realizes that the numbers on the strange drawing from Kim Jung Soo’s house was interpreted wrong. After learning that Ja Hye was at the trial of Kim Soo Hyun 10 years ago, Young meets up with her. Meanwhile, Na Ra sees Dal Rae playing with a suspicious USB and checks what’s inside.
In Ho follows Hak Bum and sees that his friends have gone too far. Hak Bum sees Ja Hye leaving his class and chases her to see why she was there. Young finds evidence that Ja Hye was at the site where Tae Suk was found with Hak Soo’s body. Meanwhile, In Ho invites Tae Suk, Hak Bum, and Ja Hye to have dinner together.
It turns out that In Ho has invited Ja Hye and Joon Hee to dinner along with Hak Bum and Tae Suk. Hak Bum and Tae Suk are surprised to see that Joon Hee has awoken. Meanwhile, Young receives a call from Suk Soon, but Suk Soon suddenly hangs up after realizing that someone has followed her.
