Special Agent Tom Hardy must assemble an elite team of scientists and soldiers to prevent the construction of a weapon so deadly a quarter of the US would have to be abandoned for decades. As the team members of the top-secret unit, known as the SOL, struggle to find the balance between duty and their personal lives, an outside threat emerges. A serial killer is torturing women, leaving their bodies a mangled mess of scars and symbols. Hardy and Dr. Jan Baker are drawn into the game of cat and mouse, as the remaining scientists and soldiers race to develop a solution to locate incoming stolen nuclear materials without alerting their enemies. Little do they know that their opposition is comprised of a deadly cadre of mercenaries, an arms dealer, a rogue IRA soldier, an assassin and a mastermind whose motivations blur the line between a revolutionary and a terrorist and revolutionary.
