Djuro Zagajski was beaten to death and left in a field outside Munich in 1983, one of roughly thirty Croat exiles killed on West German soil before the fall of the Berlin Wall. His son Robert, seventeen at the time, returns to the site on camera and describes it as a place that still symbolizes suffering. Directors Philipp Grull and Frank Hofmann trace how thousands of Yugoslavs fled Tito's socialist regime for Germany's postwar economy starting in the late 1960s, and how some were tracked down by assassins working for Belgrade's intelligence service. The film follows German investigators who spent decades trying to connect the killings to their masterminds, using secret documents and interviews with figures from both sides of the case, including officials pursuing Josip Perkovic, a former intelligence agent later indicted in Munich for the murder of Stjepan Djurekovic. Victims' families, still pressing for answers after thirty years, anchor the investigation in personal stakes rather than abstract Cold War politics.
