Cairo, 2010. As the vast city swelters in the summer heatwave, anti-government protesters take to the streets.

When visiting businessman Geoff Ward is kidnapped, his client Khaled and Khaled's sister, Layla, a prominent activist, set out to find the Englishman. Meanwhile, back in the UK, Geoff's wife, Angie, frustrated by her feelings of helplessness and the government's apparent ineffectiveness, contacts an old family friend, Shimon, to ask for help.

Who has taken Geoff and why? Can his would-be rescuers work together to find him? And how will Angie and her two teenage children cope with his disappearance?
