Heart Blackened

“Must know what happened that day.”

Lim Tae-san (Choi Min-sik) is a father who will do whatever it takes for his daughter, Choi Hee-jung (Park Shin-hye). When his fiancée is murdered and the evidence points at her, he refuses to believe it and sets out to clear her himself. Jung Ji-woo puts him up against a courtroom and a young prosecutor, Kim Dong-myung (Ryu Jun-yeol), and the two of them are left with only what each has told the other.
