Retrograde captures the last nine months of America’s twenty-year war in Afghanistan from the perspectives of the last US Special Forces units to leave, a young Afghan general and his corps defending their homeland against all odds, and the civilians desperate to flee as the country collapses and the Taliban takes over. From rarely seen operational control rooms to the frontlines of battle, to chaos in the Kabul airport during the final withdrawal, the film offers a cinematic and historic window onto the end of America’s longest war.
