Imogen visits a refugee camp in the remote mountains on the Turkish and Syrian border, and among the chaos, she seeks out Adilah, who has been separated and detained from the rest of the refugees.

Imogen and Adilah continue on their journey to Paris and face a threat in Istanbul. Meanwhile, the pressure mounts on the CIA and DGSE to determine the true identity of the "Djinn al Raqqa".

Imogen reunites Adilah with her daughter in Paris as truth and lies become further blurred.

Amidst the increased threat on her daughter's life, Adilah reveals a secret to Imogen. Max must deal with the consequences of Emir's arrival in Paris.

As the jigsaw puzzle becomes clearer to Imogen, she takes matters into her own hands. Max resorts to drastic measures whilst Emir puts pressure on Adilah.

Imogen smuggles Adilah to England to see Michael, in the hope that answers will finally be given. Max and Malik must work together and follow as her only back up.
