The Teen Killers Club is on the brink of destruction, with one faction pitted against another in a deadly game of survival. Erik and Signal are part of the group who've had their "kill switches" disabled, and the others are under orders to hunt them down--or meet their own demise. Now, Erik and Signal have to find a way to neutralize the others' switches and clear Signal's name--in the middle of a manhunt that's going viral and turning them into an Internet-age Bonnie and Clyde.
