The Roundup (1965)

Piraeus, 1944. On a quiet but restless summer night, the Nazis set up an ambush in Kokkinia, a poor commoners' neighbourhood. Before long, they manage to capture Kosmas, a ruthless black marketeer celebrating his marriage to a local girl, Antigone. And under those grave circumstances, Kosmas finds himself faced with an impossible dilemma: betray his country to save his life or pay in blood. Life is precious; however, is Kosmas truly a traitor?
