At the dawn of the Christian era, Petra, capital of the rich kingdom of the Nabataeans, bordering the deserts of Arabia, Syria and the Negev, was absorbed by the Roman Empire and, after being sacked by the Bedouins, disappeared from the memory of mankind; but its secrets are gradually being revealed thanks to an enormous excavation work.

As most plastic never deteriorates, it simply breaks down into smaller and smaller particles that are invisible to the human eye, what happens to this missing ocean plastic is a mystery. In this investigation, scientists embark in search of the micro-plastics. Small, mostly invisible, toxic, they are home to the new ecosystem: the plastisphere. But where are they? Ingested by organisms? Buried under the ocean floor? Degraded by bacteria? And what is the impact of them entering the food chain?

Chambord, the most impressive castle in the Loire Valley, in France, a truly Renaissance treasure, has always been an enigma to generations of historians. Why did King Francis I (1494-1547), who commissioned it, embark on this epic project in the heart of the marshlands in 1519? What significance did he want the castle to have?

When a huge meteorite crashed into the earth 66 million years ago and caused the disappearance of the dinosaurs, some of the planet’s tiniest species survived the cataclysm, and—against all odds—eventually became some of the greatest giants to ever roam the earth. From the poles of the planet to the belly of the equator, this documentary sheds new light on four giant animals that are still a great mystery to science today: the Titanoboa snake, the Megalodon shark, the giant rhinoceros and the giant sloth.

Two thousand years ago, it was a flourishing city in the middle of what is now a Syrian desert. At the crossroads of trade routes, Palmyra attracted caravanners from Mesopotamia, India and China. In what remains of its ruins, rediscovered by Europeans in the 17th century, its numerous necropolises bear witness to a prosperous past. Carved in limestone in the first centuries of our era, the faces of the representatives - men, women and children - of its greatest families adorn the walls of its tombs. Since 2012, Danish archaeologist Rubina Raja has been leading a long-term project to find, document and retrace the family trees and daily life of these Palmyrenians.

"Tourou et Bitti", an eight minute documentary concerning a ritual in Niger, is yet another example of Rouch's excellence in creating documentaries which surpass the conventional documentary format. Just as frightening and fascinating as "Les maîtres fous", this one goes straight into the roots of ancient African cultures, in which music has an hypnotic effect, being at the same time an exorcism and a public show. Both the female and the male dancers are almost deities about to be unleashed... Spectral and humanitarian.
