Plot – Spoilers:
A hypnotist Jijii controls a young psychopathic killer Ichi to take advantage of two gangs at war with each other. Ichi is so brutal in his hits, there are cleanup men who mop up after him.

When Yakuza boss Anjo goes missing, his next-in-command Kakihara makes it his mission to unravel the situation. Kakihara is a pure masochist and when he hears Ichi has his sights on him, it titillates him.

There are plenty of bizarre and hilarious characters in this Takashi Miike classic that was considered so violent, it was banned in many countries.
