In the spring of 1941 Yugoslavia, hitherto neutral, finds itself at war with Germany as the pro-Nazi government is overthrown and replaced by a pro-allied administration. The staff at the British Embassy make hasty plans to leave the country, but one of the military attaches, Captain Tony Davis, is separated from his comrades. Together with a motley group of refugees he escapes the city into the mountains of the west and begins a breath-taking series of adventures as he encounters the remnants of the Serb army, the dreaded Ustase terrorists and, eventually, the Partisans led by Josip Broz, alias Tito. He rapidly becomes a legend, both for his fighting ability and his capacity for survival, but his personal life is bedevilled by the rivalry between two women: earthy Croat Elena and the delicate French journalist Sandrine.
Autumn 1941: when General von Blintoft's wife is killed by a sniper's bullet meant for himself, it sparks a vendetta against Tony Davis, the legendary English officer, and his mistress. When the Germans attack the town of Uzize, Tony and Croat General Tito must plan a counter-attack.
In the spring of 1942 the Nazi-German forces occupying Yugoslavia determine to destroy the partisan army of General Tito once and for all. Unable to withstand the vastly superior forces launched against him, Tito evacuates the town and leads his people in a desperate march across the mountains in search of a safe haven. But Captain Tony Davis stays behind with a hand-picked squad - including Frenchwoman, Sandrine Fouquet, and the Bosnian, Sasha Janitz - deputed to attack enemy communications. This brings Tony into renewed confrontation with his old antagonist, SS Colonel Fritz Wasserman, and sparks a brutal conflict.
Spring 1943 and the Nazis determine to make an all-out effort to exterminate General Tito's partisans. Arch enemy of Tito's lieutenant, Tony Davis, Wassermann is determined to avenge past defeats and captures Tony's pregnant girlfriend. But can Tony reach Belgrade in time to save her?
