- How do researchers observe the physical forces at work on the Sun's surface? Can we recreate in the laboratory the nuclear fusion that takes place at its heart? What would be the impact of a major solar storm on the power grids of an interconnected world? With astrophysicists, nuclear energy researchers, historians of science, artists and hunters of the aurora borealis - a phenomenon caused by the entry of particles from the solar wind into the Earth's atmosphere - this documentary sets out to discover a star that has been a symbol of life since the dawn of humanity.
- More than 70 years ago, the Kiel gynecologist Carl Clauberg tried to sterilize hundreds of girls and women in the German concentration camp Auschwitz-Birkenau on behalf of SS Reichsführer Heinrich Himmler. Many died as a result of the inhuman experiments. The last survivors tell of the terrible experiences they had in the camp.
- From "The Little Mermaid" to "The Snow Queen", Hans Christian Andersen has left behind a rich collection of stories tinged with magic, but also with tragedy, which have kept a place of honor, from generation to generation, in children's libraries and the collective imagination. At the antipodes of the Grimm brothers' optimistic folk tales, the melancholy of his stories, sometimes crowned with a desperate end, speaks true to children and their parents alike. His tales, whose contemporary popularity also owes much to Disney, earned him immense fame from his maturity, beyond the borders of his native Denmark, even if the rest of his work (he was also a playwright, poet, novelist and short story writer) was hardly successful.
- A newly discovered 500-year-old wreck offers vital clues to the evolution in ship design that made long-distance voyages practical.

Harald Lesch explores the secrets behind the monumental buildings. Neither most nor the largest pyramids are in Egypt. In the Peruvian region of Lambayeque alone, 260 of these unusual buildings are rising. Unlike in Egypt, they did not serve exclusively as tombs of the rulers, but as palace temples. To the west of Cairo rises the only surviving wonder of the ancient world, the Pyramid of Cheops. It and its slightly smaller neighbors are among the most famous buildings in the world. For thousands of years, the monumental tombs of the pharaohs have captivated people. But the intriguing geometric shape is not an Egyptian monopoly. The emperor in faraway China also chose it for his tomb - and rebuilt entire landscapes for it. Pyramids can be found all over the world. From the Maya in Central America to present-day Iran. Allegedly, there are even 30,000-year-old pyramids in Bosnia. Why is this form found almost everywhere - among cultures that were far away in time and space, and who could not have known anything about each other? Researchers around the world have found that each culture had its own purpose for the pyramid - ranging from a tomb to a temple, from a multi-functional building to an observatory to a bloody sacrificial site. In northern Peru rise the gigantic "Gold Pyramids of Sican". Built from millions of mud bricks, their construction was an enormous collective effort, comparable to the work on the pyramids on the Nile. Archaeologists assume that the mud-brick mega-structures were not only used for religious ceremonies and as the burial place of the rulers. In the heyday of the culture, the ruling elites used the pyramids as representative residential buildings. And in times of crisis, they were probably also the scene of human sacrifices. The first emperor of China, Qin, had a huge landscape transformed into his funerary pyramid. So far, Chinese archaeologists have only partially excavated it, because it is said that there is a mortal danger inside. Rivers of mercury are said to protect the interior of the pyramid, according to old reports. And indeed, researchers have measured an increased mercury concentration in the vicinity of the funerary pyramid. The tomb became famous decades ago with the discovery of the Terracotta Army. It is one of the few excavated grave goods in the vast area of 56 square kilometers around the pyramid. What immeasurable treasures may have been given to Emperor Qin in his tomb and still slumber there untouched? In Mexico and Guatemala, new technologies are making sensational discoveries for Mayan researchers. With the LiDAR scanning process, the jungle can be digitally defoliated and shows what the ground hides under the canopy. Tens of thousands of previously unknown structures, including several pyramids, were thus revealed, providing clues as to why the great Mayan empire collapsed. Bosnia is home to the most controversial "pyramids" at the moment. Geologists see a pyramid-shaped mountain as just a whim of nature, others as a 30,000-year-old structure. For many esotericists, the Bosnian Pyramid of the Sun has become a place of pilgrimage. They are convinced that cosmic energies are at work on the mountain. Harald Lesch sorts out the arguments for or against an ancient building. Harald Lesch presents these and other enigmatic buildings in the new episode "Terra X - Unsolved Cases of Archaeology: Pyramids".
