80-year-old interpreter Ali Ungár travels to Vienna in search of the former Nazi officer who might have executed his parents. He finds only his son Georg, a bon vivant retiree who has distanced himself from his father’s past. But Ali’s visit awakens his interest, and the two men take off on a journey across Slovakia in search of surviving witnesses of the wartime tragedy.The heart of Martin Šulík’s bittersweet road movie is the superb chemistry between Peter Simonischek and Jiri Menzel (director of “Closely Watched Trains”).
