The only son of a sushi chef hates sushi and decides to leave home to search for a job and make his own way.

A young boy named Chomatsu (Misora Hibari) lives with an old man Denbei near the grounds of Asakusa temple as bell ringers. In their house is an Echigo lion mask, a memento of Chomatsu's deceased father. After several incidents of Echigo lion masks being destroyed in the area, a local kingpin Saheiji shows up at Denbei's demanded he hand over the mask, a request Denbei rejects out of pity for Chomatsu. However, after it is accidentally revealed that the mask contains an important map, Saheiji plots to steal the mask. Chomatsu gets involved after his mother makes a sudden reappearance that sends the boy on a roundabout journey that will reveal the truth about his family.
