Japan, XII century. Katsuro was the best fisherman in the whole Empire, but this did not save him from death. He delivered carp for ponds in the Imperial city and therefore had a special position. Now his young widow, Miyuki, and should replace it and deliver the remaining to the Emperor after her husband Karpov. She will be forced to make a journey of several hundred miles through forests and mountains, avoiding storms and earthquakes, when faced with the attack of the robbers and the betrayal of fellow travelers struggling with the water monsters and the brutality of people. And only the memory of happy moments from their past Katsuro will give Miyuki the strength to overcome obstacles and to convey his load to Service gardens and creeks.
