In the midst of an escalating crime spree led by a rebel army general, the Thai Police are forced to call upon their secret weapon, Yosthana - an elite agent answerable only to the highest levels of government. Faced with hired thugs who have used black magic to make themselves impervious to bullets, Yos tracks down the fabled Metal Talisman Sword, an ancient weapon said to imbue the holder with magical powers. But even if he can harness its mystical strength, he still has to save his family from kidnap, identify a traitor in his team who is selling key information and defeat his nemesis - the notorious Five Bullets Bandit - before chaos rules the city.
