CIA operative, Ridley Fox, never stopped hunting his fiancée's killers--a weapons consortium called The Arms of Ares. When an informant leads him to an old bunker outside of Groznyy, Chechnya, Fox is captured, beaten, and left for dead. When the informant rescues him, Fox learns that his capture was no coincidence: someone had set him up--possibly another government agent. Fox barely escapes after learning that Ares has acquired a hyperdeadly microbe--called Pandora--that is believed to have wiped out ancient civilizations. The trail leads Fox to Tokyo where he discovers that people within the Centers for Disease Control (CDC) and Japanese Intelligence want Pandora for themselves. The only person Fox can trust is a woman from his past who he nearly got killed.
