A reinvigorated Kobra has attacked the Justice Society in their home, thrusting the heroes into a maelstrom of deception and violence, and the evidence points to an even bigger target on the horizon: S.T.A.R. Labs. As the Justice Society tracks Kobra sleeper cells through the streets of Metropolis, the mystery of Jason Burr's master plan deepens. Can the team defuse the threat in time or will the growing tensions between them spell victory for Kobra? Continuing the new miniseries event from Eric Trautmann (CHECKMATE, FINAL CRISIS: RESIST) and artist Don Kramer (DETECTIVE COMICS, NIGHTWING)!
