Prisoner Z, held at a black site in the Negev desert for a dozen years, has only his guard for company. How does a nice American Jewish boy from Long Island wind up an Israeli spy working for Mossad, and later, a traitor to his adopted country? What does it mean to be loyal? And what does it mean to be a traitor when the ideals you cherish are betrayed by the country you love?
