Two years after exposing the Panama Papers, the investigative journalists at Germany's Süddeutsche Zeitung are facing new challenges: the political murder of the Maltese journalist Daphne Caruana Galicia and a mysterious arms dealer linked to the Iranian nuclear missile programme. Then a secret video is leaked to them in the spring of 2019, uncovering a new scandal involving Austrian Vice Chancellor HC Strache. For the documentary film Behind the Headlines, Germany's largest daily newspaper opens the door to its world-renowned investigative department for the first time, providing insight into work processes that are otherwise strictly confidential.
