When a highly-wanted hacker known as 'The Puppetmaster' begins involving them in politics, Section 9, a group of cybernetically enhanced cops, are called in to investigate and stop the Puppetmaster. The pursuit will call into question what makes a human and what is the Puppetmaster in a world where the distinction between human and machine is increasingly blurry.
