After wandering through the desert for days, a bitter warrior named Munsu is lost and unable to continue. His life is unexpectedly saved by Mon-ryon, a young man who dreams of becoming a secret agent for Jushin, a once-great country that was recently destroyed.

It is Mon-ryon's goal to save his girlfriend, Chunhyan, a born fighter who is held captive by the evil Lord Byonand.Then, from out of nowhere, blood begins trickling from Mon-ryon's chest. He has been fatally wounded by the Sarinjas, a cannibalistic breed of desert goblins. The quick-thinking Munsu convinces these beasts to spare his life, in exchange for the peaceful handover of Mon-ryon's appetising corpse.
