What is Forgotten about?
Jin-seok, 21-year-old, moves into a new house with his family. He suffers from a slight schizophrenia but he carries an ordinary life under the warm care of the family. His older brother Yu-seok is a decent college student, a mentor, and role model for Jin-seok. One night, his beloved brother is kidnapped by unidentified assailants before Jin-seok's eye. Jin-seok can’t recognize their faces, but can remember only the VIN that matches with no car. After long silence of 19 days, suddenly Yu-seok returns home, but remembers nothing which had happened in the meantime. And soon Jin-seok feels Yu-seok is a total stranger.
