Keys to the Heart

“Off-tune brothers unite!”

Kim Jo-ha (Lee Byung-hun) is a washed-up boxer with nothing left to fight for. His younger brother Jin-tae (Park Jeong-min) is a gifted pianist living with a physical disability. Choi Sung-hyun brings the two together through their mother In-sook (Youn Yuh-jung), whose stories of her past are what finally get the brothers talking, and what holds a family together when the people in it can't.
