Terrorists hold the world to nuclear ransom. Hackers, traitors, scavengers and spies are in a race against time to defuse the ticking bomb.

London, 2046. A nuclear explosion rocks the world. The SimCavalier knows exactly how it happened, and that the terrorist threat of more destruction is deadly serious. Intelligence from a coalition of cyber security leaders and a dead body floating out to sea from a nuclear facility confirm her worst fears - a familiar cybercrime syndicate is behind it all.

Cameron is desperate to protect her family and joins forces with a group of undercover hackers to fight against a rogue militia and a global cybercriminal network. Her trusted lieutenant, Ross, reassumes his old criminal identity, but is doxed by a grey hat hacker who could bring the whole delicate operation crashing down.

While the international coalition picks off the cybercriminals one by one, the terrorist militia counts down to their next attack. The pressure is on, and the stakes are as high as they can get.
