In the documentary, Churchill, Roosevelt, Stalin, Hitler and other figures who influenced the war situation appeared. The film contains detailed descriptions of important historical events that shocked the world, including the signing of the Munich Agreement, the evacuation of Dunkirk, and the Auschwitz concentration camp. In addition to using ordinary materials obtained from officials from various countries, this film also uses a large number of top-secret archive videos, civilian documentary images, and unused news videos from that year. Among them, most of the scenes about the British and French allied forces and the German and Italian fascists were shot on site by reporters accompanying the army, and are extremely precious.

In the past, the documentaries that the audience saw depicting World War II were all in black and white, but in "Apocalypse", the audience will see different color images. A large amount of black-and-white image data has been re-excavated and processed through colorization, digital restoration and other technologies. The final color image quality is extremely clear and more ornamental. The background music of this film is even more outstanding and is a masterpiece by the famous Japanese composer Kenji Kawai.
