Jonathan Pine, night manager of a luxury hotel in Cairo and former British soldier, is recruited by Angela Burr, the manager of a Foreign Office task force investigating illegal arms sales, to infiltrate the inner circle of arms dealer Richard Roper. Filming began on 19 March in Zermatt , Switzerland.
In February , it was reported that the second series was in development with Hiddleston set to return. He becomes involved with Sophie Alekan, the mistress of a playboy, Freddie Hamid, from a wealthy and influential local family. Sophie gives Pine confidential documents that she wants copied, including a list of weapons and warfare chemicals, and correspondence between the Hamids' companies and Ironlast Limited.
She tells him to keep them safe, and to pass them to his contacts if anything happens to her. This information makes its way to intelligence officer Angela Burr, who has been working to try to bring down Richard Roper, an arms dealer. However, the information is somehow leaked to Roper, who pulls out of the deal with the Hamids.
When Pine next sees Sophie, she is bruised and battered. Pine brings her to a safe house, and they become romantically involved.
Pine confronts his contact over the leaked document, and demands that Sophie be given asylum. He is told that the Hamids have numerous friends in England, so it is recommended that Sophie returns to the Hamids. A short while later, Burr discovers who provided the documents to England, and contacts Pine to rescue Sophie. Pine rushes to her room, where he discovers Sophie dead.
