Part one lays down the background, exploring the rise of Kremlin-backed trolls, Russia’s interference in Ukraine and then Vladimir Putin’s spies turning their attention to America to disrupt the 2016 vote, which Gibney calls “the most chaotic election of our lifetimes.”

Part two — co-directed with Javier Alberto Botero — is how Trump fit into all this, with the subsequent investigations into shadowy and oddball characters: Carter Page, George Papadopoulos, Michael Flynn and Paul Manafort. Remember collusion?

“Being an agent of chaos was part of Trump’s brand. More chaos, the better,” the film says.

The film has frank assessments by former officials at the National Security Council and Department of State, as well as journalists Michael Isikoff and Margarita Simonyan. Former Hillary Clinton campaign head John Podesta, whose emails were hacked, speaks of the breach, as well as former CIA director John Brennan, former Sen. Harry Reid and former FBI deputy director Andrew McCabe. Page defends himself from collusion and Trump business associate Felix Sater lays out what he knows.

The look at Russian meddling in Ukraine in 2014 is a highlight, explaining how trolls created fake news sites to drive a wedge in that country, sowed distrust, used anti-Semitism and painted opponents as neo-Nazis. The left and the right were lost in their own internet bubbles. Sound familiar?
