　　1864 After a huge battle and the brutal shelling of the population of Atlanta, Federal troops ("Yanks") take control of the city. Their plan is to use all of the goods remaining in the warehouse district of Atlanta to outfit their army for the upcoming March to the Sea, which they hope will end the War Between the States. Confederate spies move into the warehouse district, disguised as Yanks, to take stock of what is still there that might be of use to the army of the north. They find a lot. The word comes down from Confederate command to burn the entire district, destroying vast quantities of goods and uprooting hundreds of families that have been in the area for decades. "The Burning of Atlanta" is the story of the destruction of a major city near the end of the war, and the desperation and terror this causes in the lives of those who watch their entire society collapse around them.

　　Agents of Chaos, a two-part documentary from director Alex Gibney (HBO’s The Inventor: Out for Blood in Silicon Valley and Going Clear: Scientology and the Prison of Belief) examines Russia’s interference in the 2016 U.S. presidential election. Featuring interviews with key players and experts, classified information leaked by inside sources, and more, the film disentangles the complex details of Russia’s interference in the 2016 election and highlights the frightening vulnerabilities in America’s political process.
　　The film is a product of years of reporting. With never-before-seen footage inside the Russian troll farms, and videos unearthed from the Russian deep web, the film digs deep into Russia’s sophisticated plans to undermine democracy, raising the alarm for the American public, but also proving that these “agents of chaos” weren’t Russians alone; they were also key players in the United States who, through venality, corruption or circumstance, furthered Putin’s goals, with a vulnerable and unsuspecting American public as their target.
