K4oS is back. After hacking the black boxes of the national arms company with Billie at the beginning of the season, he launches his solo anarchic project: a revolutionary application that will remunerate anyone who commits an action against the political order in place. While a wave of more and more players is shaking society, Unit 42 must do everything to stop this viral application, and stop K4oS before it disappears for good. Delicate mission for Billie, plagued by contradictory feelings: her need for justice and her attachment to her youthful love.
