The documentary wants to be both a tragicomic journey into the recent history of Italy and a universal hymn to peace, but above all it proposes itself with a path that spans over a hundred years trying to fathom the difficult and even painful and ironic relationship of the people with the military world and more generally with power, in which a “pietas” of Christian origin acts strongly. All this through popular songs, archive images of the Istituto Luce and four war diaries of yesterday and today.
