The documentary reflects the events that occurred during years of Civil War between 1936 and 1939 that bled the country and left 300,000 dead, half a million prisoners and another half a million exiles.

A team of over 50 people worked for a year and a half under the direction of Francesc Ecribano and Luis Carrizo to produce an audiovisual work that narrates in an objective way one of the darkest periods of contemporary Spanish history.

The film was made possible by a laborious process of selection, digitalisation and colourising of the more than 450 films surviving from the Spanish Civil War.
