짝코(1980) / Jagko (Jjagko)

A former anti-communist policeman spends thirty years hunting the partisan leader who slipped through his fingers on one bad night, the failure that cost him his uniform and, in time, his family. When he finally corners the old guerrilla in a homeless shelter, both men are too worn down for the reckoning either had rehearsed, and passers-by cannot even work out what the two of them are shouting about.
