Totally lost and mindless, Hyun Soo shivers in the police holding cell. Just when things are looking bad, a low-life attorney shows up insisting to help. Although he does not seem very trustworthy, he is the best chance that Hyun Soo currently has. The attorney Shin Joong Han advises him of what to do and not to do while being held captive. Very slowly, Hyun Soo starts to rightfully claim his innocence.

While every step of his current situation is unfavourable and unpromising to him, Hyun Soo inevitably gets locked up in a correctional facility. Feeling scared and stranded, he tries to comply with the new rules and environment, but the reality is too harsh for an ordinary college student to handle. Meanwhile, although he has his own issues to attend to, Joong Han looks for evidence that might just prove Hyun Soo’s innocence.

Chief Park shows up at court to provide a witness statement. While questioning him, Joong Han proves that the police had been investigating this case from the get-go with Hyun Soo pinned down as the murderer. However, the prosecutor does not back down and argues that the jury and judges should focus on only the facts and not Joong Han’s story. Will Hyun Soo be released or sentenced?

Joong Han first visits Hyo Jung, Guk Hwa’s former roommate who has recently moved out not long before the incident, and demands answers to her questionable behaviour. This then leads Joong Han to people closely related to Guk Hwa one after another. Meanwhile, Hyun Soo goes through a crime scene re-enactment, but he collapses shortly after.

The last strand of hope for Hyun Soo was Joong Han until two other attorneys approached and offered Hyun Soo a questionably irresistible offer. Now that Joong Han is out of the picture, Hyun Soo works his way through the situation along with the new attorneys to prove his innocence. However, what seemed to be a good offer turns out to be the beginning of an even bigger problem.

Hyun Soo no longer has someone to rely on after claiming his innocence at the court. Eventually, Joong Han decides to step in to represent Hyun Soo when Soo Jin asks for his help. Meanwhile, Joong Han focuses on finding a potential murderer under the assumption that Hyun Soo is innocent. Hearings continue, but Hyun Soo slowly feels that his safety at the prison is in jeopardy.

Joong Han notices that something is off about other possible suspects, Yoon Hyo Jung, Um Ki Jong, and Lee Chul Ho. He finds it odd that they were not interviewed by the police, so he questions them at the court. Meanwhile, Hyun Soo’s family suffers from having to be the family of a possible murder suspect, and in prison, Baek Ho and Doo Sik start to pick a fight on Hyun Soo. And Ji Tae advises Hyun Soo to make sure to see the end of it.

The ordinary college kid Hyun Soo is excited to meet up with his friends at a pool party. To go there as fast as possible, he takes his father’s cab without even asking. As he was driving through town, a girl mistakes his cab as on-duty and hops in. Although Hyun Soo could’ve said no, he takes the girl and spends a nice night together. But that single choice he made, turns his life completely upside down.
