It is the Horeki era between 1751 and 1764. The monk Daiten Kenjo (Nagayama Eita) of Shokokuji Temple in Kyoto arrives at a toy shop where Iwajiro (Nakagawa Taishi), later known as Maruyama Oukyo, is serving his apprenticeship. Daiten becomes interested in a mysterious painting in the shop. The person who drew it is Masuya Genzaemon (Nakamura Shichinosuke), the owner of a vegetable shop at Nishiki Market. Genzaemon has completely no interest in women and traditional performing arts but is thoroughly engrossed in painting which he started at an advanced age.
