Though living with his mom and grandma, PAPA turned out to be the first word the boy Feather learned to speak. His mom told him his dad was a bird. With a natural connection with birds, Feather’s passion and affection towards birds grew day by day as he grew up. One day, Feather chased after a piece of plume he had never seen and ran into a black carrier pigeon that lost its way in the storm. Since then, this pigeon became his best friend, keeping his company all the time.Every holiday, Feather would set out together with the pigeon to look for a large grey bird and his dad. During the journeys, Feather encountered a strange boy harbouring evil intentions in the town, a teenager always by his side and a blind grandpa looking for his son.... These experiences formed a jigsaw puzzle which gradually revealed a picture filled with wonder and warmth. In one of his journeys, Feather came across an ornithologist coming back from Italy. The two of them, though meeting for the first time, seemed to have known each other for long. Would this mark the end of Feather‘s journeys?
