In a tribe venerating the sky, once a year, the villagers prepare for an event.
Putting on their sand cape, they gather to spend a moment of exchange and sharing around the same ephemeral place.
This ephemeral place is a sand castle, created thanks to their magic inspired by the relationship between the stars. It is He who has been designated «host» by the tribe, who is in charge of building the castle.
The host shows his own world, his fantasy, through a sumptuous palace filled with enigmas and hiding places.
