What do we know about the origins of the world today? This documentary presents a voyage into the mystery of these origins, accompanied by passionate scientists such as paleoanthropologist Pascal Picq, astrophysicist Hubert Reeves, physicist Etienne Klein and quantum gravity theorist Abhay Ashtekar. Organized around three key moments – the birth of the universe, the appearance of life, and the origins of mankind – this investigation takes us to various research areas around the world, including the large underground particle accelerator at CERN.
