A raid in Paris has yielded a link between the terrorist organisation Munathma and a revolutionary group called the FKA.
British Intelligence officer George Collins has been tasked to make contact with Middle Eastern student Lydia Iyad, who has links to the FKA in her country and in London.
George needs to know if Munathma have infiltrated the FKA and are planning terrorist attacks in London.
Lydia, who is only a student after all, understandably feels conflicted about the idea of spying on her friends for Britain, especially with its bad reputation in the Middle East.
George under pressure from his section chief needs Lydia to make a decision and provide information.
Will Lydia work with George or will she leave him out in the cold?
