Patriot or traitor? More than one-half century after his execution, General Andrei Vlasov remains one of World War II's most controversial figures. What prompted him to change sides and can he really be considered a collaborator? The film draws on numerous archival documents, which were previously classified and inaccessible to researchers, and on a series of interviews conducted with former members of the Russian Liberation Army, Red Army officers and diplomats, as well as former officers of the British and German armies.
