Gendarmerie, media, brouhaha, patatras... The mountain doesn't even give birth to a mouse. Would you believe it, this happened in 1999 and the mystery would have remained on the shelf of cold cases (those famous unsolved cases) if an author, a director and three actors had not taken it into their heads to re-launch the investigation by taking young spectators as witnesses. Do you have an imagination? That's what you need (as well as a good sense of observation) to carry out the investigations. We invite you to relive the five days leading up to the departure of the missing persons. On stage, our trio of investigators question us, examine reports and testimonies, sing and perform meticulous reconstructions that are as realistic as they are imaginary. Along the way, they cheerfully lead us through a forest of hypotheses with, who knows, a meeting with the mysterious "assembly of the glades" at the end... Attention, revelations!
