In this episode of Know Evil, the Firewall team draws close to an end of its time on the scum swarm but there is much work yet to be done. Existential threats, war criminals, and the swarm's leaders all threaten the team's operation. Furthermore, each member of the team is personally challenged by their own choices. How much more can they compromise to make sure their mission is a success? As they face the monsters that lurk in the shadows, can these isolated Firewall agents be sure that they haven't been corrupted as well? Perhaps by taking down a threat to all of transhumanity, they can redeem themselves. Or not. Find out what the threat is and if it is stopped in this episode!
