Taxi driver Mr. Choi buys a light bulb at a hardware store and borrows a ladder from the community center to fix a broken street lamp. After a long struggle, he is able to light the lamp. Meanwhile, his daughter is still missing. There is a saying that every law on safety is established by the bereaved. His struggling face is overlapped by many bereaved families who keep fighting to prevent the same thing from happening. (BAEK Jae-ho)
