Anna and Ben are on their first foreign posting ? to Cairo. The stress of the new job, combined with the difficulties of adjusting to an alien environment, are taking their toll. However, these problems suddenly fade into insignificance in the face of a catastrophic event which turns their life upside down and which will ultimately prove to be the catalyst that reunites them - the kidnapping of their six-year-old son, David.
Following more bombings and faced with the possibility of evacuation, Anna is desperate not to leave without finding David. She convinces Ben that their only option is to try and find the child themselves. The couple find themselves caught up in a web of oil company politics, set against a background of Islamic extremism.
