Ningyocho, located near Nihonbashi in Tokyo, is bustling all day long with its famous Ningyoyaki (Japanese-style baked goods) that attract tourists from all over the world. In this century-old old street, people live side by side in harmony and friendship. However, the calm and peaceful appearance cannot cover up the murderous intentions lurking around. One day, a woman was murdered at home. Detective Kyoichiro Kaga (Hiroshi Abe), who was newly transferred to Ningyocho, was in charge of the case. This man with sharp eyes and meticulous mind had solved countless difficult cases, but he was delayed in promotion due to his personality. He carefully investigated every detail of the case, and found that it seemed that all the businesses in Ningyocho were inextricably linked to the murder case. Everyone seemed to be lying for various reasons. Where is the truth? This film is adapted from the original work of the same name by mystery novelist Keigo Higashino.
