Heretic Monk(2006)

Gedobo

Gedoubo is an itinerant monk who roams the country subsisting with his begging bowl. However, this is a monk who has gone astray from the teachings of Buddha. His dark eyes can see the dusky black aura of the wicked! Scoundrels who have committed evil deeds in the past are unable to suppress their desires and they will repeat the same sins again. It is a fate that cannot be changed, and no one can escape its consequences…

This is the story of Gedoubo, a vigilante who will be the judge and executioner for the wicked, and the protector for the weak and helpless.
