A team of American and British counter-terrorists are tasked with stopping a terrorist cell who's operating on a global level.

The story opens with a deadly sarin attack in London. NSC counter-terrorism director Maren Jackson (Margulies) enlists FBI agent Max Canary (McDermott) and CIA Middle Eastern analyst Raza Michaels (Marek) to aid in the investigation. Acton Sandman (Skerritt), CIA deputy director of counter-terrorism, oversees the clandestine operation on foreign soil. Also on the task force is Emily Tuthill (Redgrave), director of operations for Britain's MI6; and Derek Jennings (Hill), MI5 senior director of counter-terrorism.—Anonymous
