Just as Korea gains its freedom after decades under Japanese occupation, Kim Il Sung's rise to power once again tips the scales dragging a country divided back into warfare. Kim's reputation as a fierce warrior, grants him the role of leader in North Korea's Soviet-led puppet government. His rapid rise in rank rings warning bells for anti-communist countries world-wide. But it's Korea's Civil War, North vs South, that fuel's Kim's reign of terror. Both sides scheme to eliminate the other. But after the Dictator's failed attempt on the life of the South Korean leader, the South's Central Intelligence Agency devises an assassination plot of cinematic proportions. One that will remain a closely guarded secret for nearly two decades. Why did South Korean Intelligence select civilians off the streets to be banded together on a remote island and trained as the would-be-assassins of the Dictator in the North? Classified Unit 684 was deemed 'The Decapitation Unit,' but were they ever deployed? What fates befell those trained killers? And who ultimately buried the story in order to protect the power of the South Korean President?
