In the fallout of nuclear war, the last of humanity survives with the help of life-like androids known as Dolls. Built to serve, some fight in wars as Tactical Dolls or T-Dolls. Now, an elite team comprised of T-Dolls are sent to face a new rogue threat, Sangvis Ferri. Leading them into battle is their new human commander, M4A1.

The Secret Rulers of the World was first shown on Channel 4 in April 2001. The five-part documentary series accompanied creator Jon Ronson's book 'Them: Adventures with Extremists', which covered similar topics and described many of the same episodes. Both the series and book detail Ronson's encounters following theorists and activists residing outside political, religious, and sociological norms.
