오발탄(1961) / Aimless Bullet ( Obaltan )

An accountant supporting a mother unhinged by the war, a malnourished pregnant wife and a sister working the camptowns finally cracks when his brother is arrested for a botched bank robbery and his wife dies in childbirth the same day. He ends the film in a taxi with a freshly pulled tooth and nowhere to go, still muttering the refugee's old command to move.
