On Christmas Eve, retired cyclist Gin, perverted Hana, and runaway girl Miyuki were doing nothing in the snowy night of Tokyo. At this time, they found a crying abandoned baby in the garbage dump. The child's swaddling clothes only contained a bar's business card and photo. The identity of the baby's parents became a mystery. Hana wanted to take the child in and named the child Kiyoko. But the other two objected. So the three began their journey to find Kiyoko's parents. The happy atmosphere of Christmas Eve was accompanied by Kiyoko's crying in her arms. The three homeless people began to look for a home for Kiyoko, who was also homeless. This group of wanderers experienced many strange events in one night. Can they find Kiyoko's parents?
