Documentary filmmaker Cullen Hoback sets out to demystify the origins of QAnon, understand its mechanics, and search for clues that could identify Q. Traveling from the U.S. to South Africa, he gains unprecedented access to its earliest promoters, who reveal a suspicious shift in Q's behavior.

Cullen travels to Manila where he meets the secretive team behind 8chan, the site where Q posts. After looking into Fred Brennan's motives for starting the site, the investigation turns to Jim and Ron Watkins, the reclusive father/son duo who own and operate 8chan. Back in the U.S., prominent QAnons get booted from a far-right conference.

An anonymous insider gives Cullen a tip suggesting 8chan may have ties to Trump's inner circle. A rivalry emerges between old allies.

Jim goes before Congress for a hearing on hate speech. Cullen chases a lead suggesting Steve Bannon might be involved with Q.

As QAnon-fueled conspiracies culminate in the U.S. Capitol siege, Cullen reveals the forces behind Q.
