The Outrage (2010)

The plot concerns a struggle for power amongst Tokyo's Yakuza clans, today just as likely to be playing the stock market as shaking down pachinko parlors, over which the Sanmo-kai clan holds sway in the face of constant betrayal and ever-changing allegiances. The Sanmo-kai chairman learns that his henchman Ikemoto has struck an alliance with the drug-dealing Murase family, and is not best pleased, to say the least. The ensuing retaliation triggers an orgy of killings, territorial invasions and score settling while law enforcement officers are too corrupt to intervene.
