It was Golden Age for international travel, a decade when advanced transport systems allowed people to journey all over the world. Travellers with the means recorded their experiences by using the new colour film technologies. Often unintentionally, their home movies captured defining moments at a time when the nations of Europe were about to be plunged into the disaster that was The Second World War. The final episode features colour films shot by travelling film-makers in Europe, including footage shot on the streets of Berlin decked in red swastikas at the time of the Olympic Games, rare pictures of the Jewish quarter in Warsaw just weeks before the Nazi invasion and, in London, tourists wearing gas masks amid fears of imminent bombing raids by the German Luftwaffe.
