After a brief
voice-over by Jacques Pruvost describing the
bombing of Guernica on 26 April 1937,
María Casares recites a poem by
Paul Eluard on the subject of that atrocity, accompanied by imagery from numerous paintings, drawings, and sculptures produced by
Pablo Picasso between 1920 and 1949, particularly
Guernica (1937). The oppressive musical arrangements in the film were composed by Guy Bernard. ==Home media==
