Nessa Stein is a beautiful and powerful Anglo-Israeli businesswoman who strives for equality and peace in the Middle East, heading up the powerful Stein Foundation with her brother Ephra.

With the hunt on for Atika's son, the head of MI6's Middle East desk Sir Hugh Hayden-Hoyle starts to look into who killed Meshal and why.

With Dame Julia having steered him in a different direction in order to get to the truth, Hayden-Hoyle turns his attention to Nessa.

Nessa’s security advisor follows a lead he believes will help him uncover the identity of Kasim’s kidnappers -- however, Nessa is forced to reveal this to her mysterious caller.

Going back eight years, we see a younger Hayden-Hoyle making his way to the top of the spy business courtesy of an affair with current MI6 chief, Dame Julia Walsh.

Nessa makes a chilling discovery concerning a wiretap on the Stein data cable, an alarming fact that the professor also inadvertently stumbles across in the basement of the University.
