Donald Trump became the 45th President of the United States by winning three key states, a victory engineered by an ultra-conservative faction that quietly mapped its way to power using fake news, lies and psychometrics. This explosive documentary follows the money to the reclusive multi-billionaire Robert Mercer who bought Breitbart News and funded the effort, while inserting Steve Bannon into the presidential campaign as its manager. Using data of millions of Americans acquired from Facebook, Google, banks, credit companies, social security and more, another Mercer company, Cambridge Analytica, used tactics honed during the UK's Brexit campaign to identify voters deemed most neurotic or worried, whom they believed could swing for Trump. In the days before the election, using a little-known Facebook feature, dark posts, they deployed highly manipulative and personalized messages, that could be seen only by the user before disappearing. In the darkness of the web, democracy was trumped by data.
