In the cave of Lascaux in France a drawing was found on the wall. This can not explained nor exist any good theory about it's meaning.
Here a reconstruction-by-doing is an attempted in order to make the drawing a part of experience today - some kind of actualization.
Original drawing can be found as a very good photo in the book of Mario Ruspoli: "Lascaux - un nouveau regard" publisher : Bordas, Paris, ISBN 3-8289-0664-8 (german edition by Bechtermünz Verlag)
The drawing is visible in the beginning and end of the film as a sketch by the artist.
