'The Yakuza's Law Lynching' (1969) - Teruo Ishii.

This rousing, splendidly blood-thirsty portmanteau of lurid Yakuza conflict erupts in a bloody tsunami of gruesome eye-gouging, grisly evisceration, bravura throat slashing and super-sanguineous Katana kills! Maestro, Teruo Ishii's infamously brutal trilogy of dramatically vengeful, gratuitously gore-grizzled Yakuza mayhem has manifestly lost none of its power to shock! Dynamic performances, visceral action scenes, diabolical treachery, desperate love, and hard won honour, 'The Yakuza's Law Lynching' is eventful, intelligent, bracingly violent Japanese exploitation at its most excitingly mean spirited. Vicious betrayals, Machiavellian plots, and savage, bullet-blasted reprisals,'The Yakuza's Law Lynching' remains entirely credible, a brutish, extraordinarily bellicose, generously crimson-splattered, eye-bogglingly cruel Torture classic. These three indelibly barbaric tales graphically portray the grimly mortal fates of those individuals who break the gleefully enforced Yakuza laws, since they do so at their own considerable peril!
