World on Fire

Summer 1939. Translator Harry is working at the British Embassy in Warsaw, falling in love with Polish waitress Kasia. When German tanks roll into Poland and Britain declares war on Germany, Harry and Kasia are faced with terrible choices.

A month into war and with Warsaw destroyed, Harry is desperate for news. Meanwhile Kasia joins the Polish resistance.

December 1939, and Tom fights for his life on board the HMS Exeter at the Battle of River Plate. Meanwhile, Harry and Lois have a more personal battle to fight.

Harry's courage is tested at Louvain as he comes face to face with a German sniper, and Kasia's resistance activity in Warsaw intensifies.

As thousands flee Nazi-occupied Belgium, Harry, Stan and the rest of their unit take the last route out of France - the road to Dunkirk, where Grzegorz fights his way to the front of a queue to board a boat - only to be thrown back by angry soldiers. In Manchester, Douglas finds solace in his rapport with Jan, as his growing anxiety about Tom pushes him to the brink, while in Berlin the Rosslers grow ever more fearful for Hilda.

June 1940. The Nazis have taken Paris with not a bullet fired. Webster and Albert's life in the city they love will never be the same again.

Harry has a second chance at saving Kasia from Warsaw. In Manchester, could Lois be set for happiness at last?

The war reaches the sands of the Egyptian desert, while bombs fall on Manchester, and Harry introduces an explosive force into Robina's household, leaving her reeling.

As Harry struggles to adapt to the reality of desert combat, Lois still longs to leave home. In Paris, Henriette is in grave danger, and a mysterious stranger arrives at Robina's.

As Stan and Rajib make a hasty retreat across the desert, Marga reasserts her commitment to the führer. Meanwhile, David is in peril in the skies over France.

As Kasia takes on her first assignment as an agent, Rajib's military values are tested. Meanwhile, a familiar face comes to David's aid.

Tragedy strikes at the heart of Harry's unit as the siege drags on in Tobruk. In Manchester, Kasia is confronted by more of the horrors of the war. In France, romance blossoms between David and Henriette.

Harry returns to Manchester, but Kasia is determined to leave. In Europe, Marga and Henriette must each make their escape, while north Africa becomes even more brutal for Rajib.
