People You May Know follows Charles Kriel, specialist advisor to UK Parliament on disinformation, when he discovers Cambridge Analytica collaborating with a software company creating a microtargeting platform for US churches, targeting vulnerable people - the poor, the grieving, the addicted - to radicalise them for far-right politics. With US 2020 elections coming, Kriel gathers a team of whistleblowers and journalists, and journeys across America with his young family, where he discovers a powerful organisation with ties to the heart of the White House. The man who commissioned CA is a member of the most powerful secret political organisation in the United States, with an agenda to rewrite the Constitution according to Christian law. Going undercover, he risks everything to gain access where no outsider has ever set foot.
