Osamu, a gangster who works for "Ayabe Information Services" as a "private detective", is given a very interesting job: he has to pretend to rob a jewelry store, hide the "goods", and let himself get...
Osamu is hired to play a "real" yakuza and deal false cards to a group of gamblers. Unbeknownst to him, the client is using him to dominate the others in the group.
Two lovable idiot "private detectives" (or at least, that's their cover story —more like gangsters) try to make ends meet on the mean streets of Tokyo.
