Inspired by the book by Robert Littell, this historical miniseries follows rookie CIA agent Jack McCauliffe (Chris O'Donnell) as he trains under the watchful eye of mentor Harvey Torriti (Alfred Molina), aka the Sorcerer, during the Cold War. Meanwhile, fellow agent James Angleton (Michael Keaton), aka Mother, is driven to a near-breakdown by the hunt for a mole in the agency. Alessandro Nivola and Natascha McElhone co-star.
