In Cairo at the height of the Arab Spring, hotel night manager Jonathan Pine (Tom Hiddleston) receives a plea for help from the beautiful Sophie Alekan (Aure Atika). As the mistress of the powerful but dangerous hotel owner, Sophie has evidence of an arms deal that could help crush the popular uprising. Compelled to do what he thinks is right, Pine makes contact with his friend at the British Embassy. But his actions unwittingly draw him into the terrifying world of ruthless arms dealer, Richard Roper (Hugh Laurie). When Sophie's information makes its way to Angela Burr (Olivia Colman), a government anti-corruption agent intent on bringing down Roper's empire, a leak in her network triggers a chain of events that end in tragedy.
