El Perro Negro - Stories from the Spanish Civil War is a poetic collage of homemade movies, captured almost involuntary by amateur artists. Joan Salvans i Piera and Joan Ernesto Díaz Noriega are the two characters of this story: Ernesto, a middle class student in Madrid, who survives war; and Joan, a Catalan industrialist who is murdered six days after the outbreak of the conflict. Their films lead us through the Spain of the 30s and 40s.
