The Kingdom is the most technologically advanced hospital in Denmark, a gleaming bastion of medical science.

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.
