This story begins with a photo taken a century ago during the colonial era. The director goes to Yeongdeungpo with a camera to find any trace or signs of factory girls in the photo. There are no large factories anymore, only apartments, department stores, racetracks, inns, steel factories, restaurants, unidentified places, or empty ruins. Through the lives and landscapes of Yeongdeungpo, the director wants to discover any traces that factory girls might have left. The remaining factory fell into decay as it has been exposed to lights for too long. The building has had no visitors for so long that it has become a house for pigeons with nowhere to go. Later, the director meets the families of the factory girls. The director looks into the lives of the girls that their families remember and finds the traces in their gestures and facial expressions. There, the director meets the girls who survived. What they went through during those fraught times is marked on the faces and bodies of the girls, Oksun and Boksun.
