The "big six" are the most important raw materials of the future: geologist Colin Devey is traveling through the desert country of Jordan. Here he finds urgently needed raw materials for a climate-neutral world of tomorrow. Whether wind turbines or electric cars, the more CO2 is to be saved, the more metals are needed for green technologies. The Stone Age ended with the discovery of copper in the Middle East. A new chapter begins for mankind, one that is still characterized by metals today. Copper is a kind of "Holy Grail" for the electrification of our everyday lives. Chile is home to the largest known copper deposits. They are the result of a continental collision.

In the name of Hitler, more than 13 million Europeans – in many cases mere children – were taken from their homes and forced to work for the enemy, Nazi Germany. This phenomenon was not confined to concentration camps: there was no German town, no German village that did not have forced labourers. From numerous international perspectives, this series traces the story of both, the victims and the perpetrators.

The Italian Mafia is often referred to as an octopus, its many arms symbolising the clan’s countless branches, with which it ominously and sinisterly penetrates all areas of society. But Italian investigators consider this comparison dangerous and erroneous, as the Mafia rather more resembles one of evolutionsmost intelligent entities: the parasite. This documentary, based on Sicilians in their campaign against the world’s oldest Mafia organisation, the Cosa Nostra, explains how it succeeded in penetrating the brain of the system like a parasite. In doing so, barely known chapters of recent Italian history are brought to light. The documentary shows the example of the Cosa Nostra, the Mafia is now a global company and their influence despite all search successes of recent years rather than growing waning.

Submarines today are highly complex machines crammed with technology and weapons. As impressive as their construction is, as terrifying is their destructive power. Hardly any other weapon triggers as many emotions as the submarine. It strikes from ambush and can use nuclear missiles to drag the whole world into the abyss.

Submarines originated from a completely non-military idea, namely to be able to view the world under water. But the interest in the military use of submarines soon prevailed.

On the Battlefields of the World Wars: Since its invention at the start of the 20th century, the tank has served as a symbol of political power as well as military strength. These huge vehicles have long since found their way into global culture - whether as a monument, in films or on billboards. Tanks have made history and have themselves become part of the story.

This five-part series hears the testimonies of former members of the Hitler Youth and draws on unpublished archive material and chilling propaganda footage for the first comprehensive film portrayal of the young people of the Third Reich.
