특별수사본부 외팔이 김종원(1975) / A Special Investigator, One-Armed Kim Jong-Won

A commander running his own cell inside the outlawed Namrodang is set up by the party leadership, defects to the special investigation bureau, and takes the network apart piece by piece. Lee Won-se ends not on vindication but on a man acquitted of everything and left with nothing to want.
