Private Detective DOBU 3: The Exile Island Murder Case

Six men were pardoned and returned to Edo from Hachijojima. However, four of them are killed one after another. Only two remain. Kosuke (Koichi Miura), a pickpocket, who is also the junior of Osen (Kilin Kiki), as well as Kingo Shimura (Tsutomu Isobe), who had been sent to the island after killing a blind person. Since all of them were stripped of their clothes and killed, Dobu (Kunie Tanaka), an Okkabiki, suspects that the gang of murderers is "looking for something"..
