Blind

In the city of Muyoung, the body of a young woman in her twenties is found near a greenhouse complex. The perpetrator leaves a gruesome signature by slashing the corners of her lips. Detective Ryu Sung-Joon, driven by rage, becomes relentless in his pursuit and captures the suspect. Despite overwhelming evidence pointing to him, the suspect claims his innocence and demands a jury trial.

With overwhelming evidence against him, Jung Man-Chun is identified as the killer. The nine jurors unanimously find him guilty, and Judge Ryu Sung-Hoon sentences him to life imprisonment. That evening, the jurors gather for a dinner at Charles's restaurant.

During a tense standoff, Ryu Sung-Joon and Jung Man-Chun are injured and hospitalized. While they are recovering, another woman's body is discovered in a park, bearing the same gruesome signature as the first murder. Is there a copycat on the loose, or did the real killer remain at large?

Baek Moon-Gang seeks revenge on Jung Man-Chun for his daughter's death and confronts him in the hospital. Feeling threatened, Jung Man-Chun reveals a shocking truth: a person named "Yoon-jae" orchestrated everything. Moon-Gang recalls a boy with number 13 from the "Hope Welfare Center" and begins to suspect that Ryu Sung-Joon might be that boy.

Framed for the murder of Jung Man-Chun's family, Ryu Sung-Joon is on the run. Jo Eun-Ki is the only one willing to help, hiding him in a warehouse at her children's center. She seeks help from Ryu Sung-Hoon, who agrees to meet Sung-Joon.

The brothers secretly collaborate to catch the real killer, "Yoon-jae," and clear Sung-Hoon's name. As they track the killer, a child from Jo Eun-Ki's center, Yuna, is brutally attacked. Sung-Joon identifies the suspect, Choi Soon-Gil, from Yuna's drawing of a tattoo and confronts him, finally uncovering a crucial piece of the puzzle.

As new evidence emerges, the case grows more complex. The jurors gather at the wedding of Kang Young-Gi's daughter, only for another terrifying incident to occur, throwing everyone into panic. Was this all a meticulously planned revenge plot targeting the jurors from the start?

What is the connection between the killer and the "Hope Welfare Center"? What ties do they have with the jurors? Suspicion falls on all the jurors as they each receive the same cryptic text message.

With Ryu Sung-Hoon's help, Ryu Sung-Joon is cleared of suspicion but still faces many unanswered questions. Then, Jo Eun-Ki delivers shocking news: "Yoon-jae is dead!" How could this be?

Sung-Joon discovers that Jo Eun-Ki's mother was a nurse at the "Hope Welfare Center." He visits her for an investigation, and she becomes visibly anxious upon seeing him. That night, Sung-Joon rushes to the children's center after receiving an urgent call from Eun-Ki. Is Eun-Ki in danger?

Sung-Joon tracks Sung-Hoon to save Jo Eun-Ki, but his expectations are upended. A mysterious person reveals identity to Sung-Hoon.

Jo Eun-Ki, sensing that the person Yuna mentioned in her dying message might be the killer, shares her suspicion with Ryu Sung-Joon. Sung-Joon also finds clues pointing to the same person.

Suddenly, Jo Eun-Ki and seven others are kidnapped. Are they taken by the same person they have been searching for, or is it someone new? Can Ryu Sung-Joon save them before it's too late?

What really happened at the "Hope Welfare Center" 20 years ago? As Na Gook-heui and Yeom Gi-Nam become increasingly anxious, they find themselves drawn deeper into the web of secrets and lies that surround the case.

Ryu Sung-Joon discovers through court records that his father, Ryu Il-Ho, was the judge in the "Hope Welfare Center" case 20 years ago. He confronts his father, seeking answers to long-buried questions.

As all the truths are revealed, Ryu Sung-Joon witnesses the final moments of his family, while Ryu Sung-Hoon, with no way to retreat, faces the last tangled web of their fate. The brothers must confront their past and each other to find closure.
