On the 6th of January, 2021 thousands of Trump supporters stormed the United States Capitol. Their banners read, Trust the Plan, a reference to an alarming conspiracy theory that had gained unstoppable momentum over the last four years: these were followers of QAnon.

Decoding online clues from a mysterious figure – who has claimed to be a high-level government insider – QAnon adherents believe that Donald Trump has been anointed by God to stop a depraved deep state government, that sexually abuse, kill, and eat children. But QAnon has also become a broad church of out-there beliefs, offering a welcoming community to anti-vaxxers, flat earthers, eugenicists and white nationalists.

With first hand access to the leading figures in the movement, investigative journalist Will Sommer unpacks the bizarre story of how a post from one of the darkest corners of the internet, became a belief system for millions; how politicians cozied up to extremists; how an unwavering trust in these ideas tore apart families, caused a mafia boss’s assassination, and threatened democracy. Trust the Plan is a timely and essential look on how the internet radicalised our politics, and how millions were convinced to believe the unbelievable.
