Dobu (Kunie Tanaka) used to be a soldier but now is a private detective. Three vagrants were killed in a shrine, and Dobu found out that those three had a grudge on a timber whole seller, Hinokiya. He reunited with Zirokichi (Takeo Chii), one of his friends and Nezumi Kozo (a thief) , and he infiltrates Hinokiya together.
Sorry, but for now we weren't able to find movies like Private Detective DOBU 1.
