During the period that goes from 1945 to 1965, the filmmakers Lino Del Fra and Cecilia Mangini lived for three months in the Northern Vietnam during the USA war, in order to produce a documentary about the Vietnamese people. Now, two boxes full of 6x6 format photographic negative, forgotten inside an old closet for more than fifty years, have been found. The discovery has created a chamber movie that tells the story of a war, of a fading memory, and of a fight against time passing.
