Yeon-ho's life takes an unexpected turn when he finds a news clip in his mailbox, recounting a tragic accident involving a driver who ran over a married couple. The chilling familiarity of the report sends him into a spiral of memories, transporting us back to October 2014.

The funeral scene, where Hyun-soo's grieving parents confront Yeon-ho's family, is a poignant reminder of the human cost of a moment's inattention.
In the present day, the TCI team is confronted with a new case involving a woman, Kim Min-ju, who fell out of a moving car driven by Yang Jae-young. The team's investigation reveals a complex web of power dynamics, sexual harassment, and a desperate struggle for justice. Min-ju's plight and her subsequent decision not to press charges against her powerful harasser underscore the systemic challenges faced by victims in seeking redress.
Yeon-ho's personal journey runs parallel to the team's case, as he grapples with his own past and the mysterious news clippings that have resurfaced.

The tension between Yeon-ho and Myung-hak is palpable, as their shared history casts a long shadow over the present.
The episode also explores the dynamics within the TCI team, as So-hee takes on the role of a mentor to Yeon-ho, teaching him martial arts in a series of humorous yet insightful training sessions.
