Lacuesta and film director Pere Vilá followed the stages of the work conducted by a team in 2003 when they excavated - for the first time according to scientific and archaeological criteria - a mass grave in Cataluña dating back to the Spanish Civil War. The film shows the research on a recent, however hidden and buried, past; and a careful and painstaking excavation, carried out by way of controlled and accurate movements. It is a film about time, history, and the present.
