"We have to return to justice and law instead of engaging in war – if not we will destroy the whole world." This was the credo of the last living chief prosecutor of the Nüremberg trial against criminals of war and peace activist Benjamin B. Ferencz. The film portrays this still very engaged 95 year old. Historic film documents, very personal interviews with him, statements from colleagues and friends as well as a camera, which follows this restless protagonist around the world, make this film an adventure through the life of this charismatic man.
