This Oscar-winning documentary follows Russian opposition leader Alexei Navalny as he and his team unravel a plot to poison him with deadly nerve agent novichok. In August 2020, a plane travelling from Siberia to Moscow made an emergency landing. Alexei Navalny was deathly ill. He was taken to a local Siberian hospital and eventually evacuated to Berlin. Doctors there confirmed that he had been poisoned with 'novichok', a nerve agent implicated in attacks on other opponents of the Russian government. President Vladimir Putin immediately cast doubt on the findings and denied any involvement. While Navalny is recovering, he and his team uncover the plot against him, finding evidence of the Kremlin's involvement, and prepare to go public with their findings.—'BBC'
