Just outside Paris, in a peaceful clearing surrounded by woods, a French flag flies above a bare concrete pad. Here, on February 21, 1944, Nazi occupiers executed 23 Resistance fighters by firing squad. After the executions, the Nazis highlighted many of the murdered fighters on a notorious red poster, labelling them as foreigners, communists, and Jews. 23 FOREIGNERS — OUR BROTHERS tells the stories behind some of the faces on that poster, exploring their lives through archival photos, letters they wrote on the eve of their deaths, and moving interviews with their descendants.
