When a Yakuza boss named Anjo disappears with 300 million yen, his chief
henchman, a sadomasochistic man named Kakihara, and the rest of his mob
goons go looking for him. After capturing and torturing a rival Yakuza
member looking for answers, they soon realize they have the wrong man
and begin looking for the man named Jijii who tipped them off in the
first place. Soon enough Kakihara and his men encounter Ichi, a
psychotic, sexually-repressed young man with amazing martial arts
abilities and blades that come out of his shoes. One by one Ichi takes
out members of the Yakuza and all the while Kakihara intensifies his
pursuit of Ichi and Ichi's controller Jijii. What will happen as the
final showdown happens between the tortured and ultra-violent Ichi and
the pain-craving Kakihara?.
