Official SelectionSynopsis:
A whale existed 5 million years ago. Mark found her skeleton and decided to reassemble the pieces in a dusty basement of the Science Museum in Brussels. A filmmaker found Mark and decided to film him, the whale, and the dust. While these bones are put back together, like pieces from a puzzle, we try to imagine how life was 5 million years ago, a time before humans existed, but the sea and the sun were already here.
