After witnessing his father’s brutal murder at the age of nine, Park Soo-Ha develops the uncanny ability to read minds. The only person who ever stood up for him was Jang Hye-Sung, a teenage girl who risked everything to testify against the killer. To Soo-Ha, she became both a hero and his first love. Ten years later, Hye-Sung, now a public defender hardened by cynicism and a painful past, has forgotten the boy she once saved until he walks back into her life. Reunited under strange circumstances, Soo-Ha and Hye-Sung begin working together in the courtroom alongside Cha Kwan-Woo, a warm-hearted former cop-turned-idealistic lawyer. As they take on cases that challenge injustice and moral ambiguity, an old threat resurfaces. Min Joon-Kook, the murderer who once shattered their lives, is released from prison, and his promise of revenge remains unbroken. As their personal and professional lives collide, the trio must confront painful truths, unhealed wounds, and the high cost of justice when vengeance strikes too close to home.
