Heart Blackened

Heart Blackened is a 2017 South Korean crime drama film starring Choi Min-sik, Park Shin-hye, Ryu Jun-yeol, and Lee Hanee. It is a remake of the Chinese film Silent Witness.

Synopsis
Im Tae-san (Choi Min-sik), a man with wealth, love and the world, believes that everything is perfectly happy. His fiancée and famous singer Yoo-na (Lee Hanee) is murdered, and his daughter Im Mi-ra (Lee Soo-kyung) is pointed out as a suspect. Lim Tae-san starts pursuing the case in his own way to make her daughter innocent, who cannot remember what happened that day. He appoints a young lawyer, Choi Hee-jeong (Park Shin-hye), who believes in Mira's innocence and cares for her, refusing the best lawyers. A fierce court battle surrounding the 7-hour truth — that Mira doesn't remember, but the existence of Yoo-na's fan Kim Dong-myeong (Ryu Jun-yeol), who has CCTV footage of the day that disappeared — is revealed and the case goes in an unexpected direction.
