Ireland, 1849. The country is currently in the midst of the Great Famine. Triggered by a potato blight, hundreds of thousands have perished from starvation and other fatal ailments. Under these conditions, paying rent has grown difficult for farmers, leading to the eviction of many from their land. Two individuals caught in this grim situation are Amelia, a frail 14-year-old girl, and her servant Connor. Their family's land was seized, forcing the pair to struggle while living as vagrants. However, just across the sea, a rather lucrative event is unfolding—the California Gold Rush. With aspirations of becoming millionaires, Amelia aims to turn both her and Connor's lives around. They decide to travel to America, hoping for a life free from future hardships. Katabami to Ougon is the story of two refugees as they venture outside of Ireland, with only their hopes and dreams pushing them forward.
