The best way to escape from your pursuers without leaving any traces behind you is to walk backwards over your own footprints. This is what French artist and author François Augiéras believed as he painted every inch of the walls of a military bunker in the desert and let it sink into the sand so that no-one would find it till the 21st Century. But who is Augiéras? A legionary, painter, writer, gunman, saint, thief, devil, or a mix of all this?

One of the most interesting auteurs working in Spain today, Catalan filmmaker Isaki Lacuesta, and one of Spain’s foremost living artists, Miquel Barceló, guide us through the Mali desert in search of a fresco painted by Augiéras in this gorgeous film that won the Golden Shell (Best Film) at the San Sebastian International Film Festival.
