Maggie Gyllenhaal discusses her role in the new SundanceTV miniseries “The Honorable Woman,”  about Nessa Stein, whose father was a Zionist arms procurer who was assassinated. Years later, after inheriting her father’s company, Nessa changes its purpose from supplying arms to laying data cabling networks between Israel and the West Bank, promoting peace and communication. Her work earns her an appointment to the House of Lords. When a secret from her past threatens to be exposed, she realizes that those closest to her are potentially her most dangerous enemies. “The Honorable Woman” premieres July 31 at 10 pm on SundanceTV.
