An investigation surrounding a serial bomber takes an unexpected turn when suspects mysteriously commit suicide after relaying absurdly specific messages to Chicago's FBI Special Agent Kerry O'Malley and CSI Lieutenant Justin Finch. Kerry fails to heed her brother Neil's warnings to cease the investigation, and he eventually reveals the truth to her: he has kidnapped a child from the Group mastermind known as the Wizard. The child was critical to the very plan the Council was formed to sabotage, and Neil's action brings rapid retaliation. The Wizard arranges for Kerry's capture and infection with a virus that will kill her in less than two days unless the Council returns the child. Her team rushes to save her while the Council sets its eyes on the larger goal of bringing down their rival Organization before the Wizard can use it against them. Thus begins the inevitable conflict that will determine whether mankind's freedom remains intact or is erased forever.
