From 1937 to April 1945, in the Buchenwald - Dora - Kommandos concentration camps complexe, more than twenty artists-deportees managed to secretly draw their living conditions.This is the work this documentary would like to examine: the conditions of its creation, the images it represents, the struggles it portrays and its circulation since that time. And quite simply to show it as a whole for the first time since the liberation of the camps, letting people see it in all its intricacy, confronting it with other pictures of these camps ; exhibiting it alongside what is left to see, there, in the remains of the camp ; searching for it too, in the places where it has been preserved – scattered, we should say - now.
