The story takes place near Pusan, South Korea, several months after the beginning of the Korean War. A family (a father, mother, boy, and a dog) of farmers has fled from their homes in Sang Po, and now live under a bridge. The father is very traditional, wearing a gat, while his son is more modern, having learned how to make money off of the "long-nose" American soldiers (by shining shoes and leading them to "Shibi-Shibi" girls—prostitutes—to be serviced), going so far as to adopt parts of their jargon. The mother takes pride in her son's money making skills, and views her husband as weak, much to his chagrin.[5]
The family is destitute, but plans to return home by train. Their dog, however, is sickened after being over-fed by soldiers, and at the station the son refuses to part with him. In an ensuing confrontation, the father's gat is knocked off, revealing him to be a young man. This draws disparaging comments from the crowd, as most young men have been drafted to fight in the war; many assume that the father only wears his gat so that he can pass as an older man and avoid having to fight. The father, angered and frustrated by the lack of respect being shown to him and his heritage, chooses to walk back to Sango Po, telling his family to take next day's train.[5]
The mother and son return to their bridge to find it occupied by another refugee woman. The dog's condition worsens, and the boy wanders a nearby town, which is filled with churchgoers and "Shibi-Shibi" girls pairing with their American lovers. After military police scatter the prostitutes, the boy finds his mother among them. Despairing, he flees into the countryside, followed by his mother and his dying dog. The dog soon collapses, whereupon the mother and son silently stay with him. At nightfall, a passing elderly farmer allows the dog into his horse-drawn cart, promising to bury him when he dies. He tells the couple a story about the origin of the gat - explaining that the garment was intentionally designed to be delicate and easy to knock off so as to deter men from fighting. The son walks off, realizing he can never reveal what he has learned that night.[5]
