Jidanya (1963)

Every day a car accident happens in the city. The involved parties are prey to the settlement agents (jidanya), mediators between the parts and the insurance companies to avoid time-consuming legal actions that could come when no settlement is reached (while cheating both parties out of some piece of the settlement pay). Genkichi is a well versed old-timer, that sees how his freshly out of collage son struggles to fit into the business, while at the same time facing one of his lowest rivals in a car crash incident.

Unfortunately the movie Jidanya is not yet available on HBO Max.
