RETROGRADE captures the final nine months of America's 20-year war in Afghanistan from multiple perspectives: one of the last U.S. Special Forces units deployed there, a young Afghan general and his corps fighting to defend their homeland against all odds, and the civilians desperately attempting to flee as the country collapses and the Taliban take over. From rarely seen operational control rooms to the frontlines of battle to the chaotic Kabul airport during the final U.S. withdrawal, Oscar-nominated and Emmy Award-winning filmmaker Matthew Heineman's latest film offers a cinematic and historic window onto the end of America's longest war, and the costs endured for those most intimately involved.
