Japan, XII century. Katsuro was the best fisherman in the entire empire, but this did not save him from death. He supplied carp for the ponds in the imperial city and therefore had a special position. Now his young widow Miyuki must replace him and deliver the carps left behind by her husband to the emperor. She will be forced to travel several hundred kilometers through forests and mountains, avoiding storms and earthquakes, facing the attack of robbers and the betrayal of fellow travelers, fighting water monsters and the cruelty of people. And only the memory of the happy moments of her and Katsuro's past will give Miyuki the strength to overcome obstacles and bring your burden to the Gardens and Creeks Service.
