A stone lies in a dry, abandoned place on the outskirts of Barcelona, in the middle of a mountain that's no longer a mountain. Thousands of years ago it was used as a place to leave offerings. Sacrifices were made here as petitions for good omens. The stone recalls the last shepherd in the area, the only one who visited it, before disappearing with his sheep. In the midst of an eternal summer, suddenly, a visit interrupts the stone's existence.
