Spain, July 1937. The tragic prelude to World War II is played out in the civil war between Spanish nationalists and republicans. Among Franco's volunteers is Martin Bora, the twenty-something German officer and detective. Presently assigned to the Spanish Foreign Legion, Bora lives the tragedy around him as an epic, between idealism and youthful recklessness. Doubts about his mission in Spain arise when Bora happens on the body of Federico Garcia Lorca, a brilliant poet, progressive and homosexual. Who murdered him? Why? The official version does not convince Bora, who, intoxicated by the mystery, begins a perilous investigation. His inquiry paradoxically proceeds alongside that of Walton, his opposite number with the International Brigades. Soon the German and the New Englander join forces, and their cooperation will not only culminate in a thrilling chase after a murderer, but also in an existential face-to-face between two adversaries forever changed by their encounter. Historical accounts tell us that Lorca was arrested and executed by Franco's troops under circumstances that remain largely unknown. To this day his body has not been found.
