In a parallel dimension where music once existed, Pesadilla feeds on the galaxy's fear. Somnus is no longer a safe world; its natural satellite Disnomia has been seized for sinister purposes. The planetary system is threatened by darkness, shadows cover everything except for a powerful and mystical light emanating from the central planet. Fantasía has sent the chosen Doppel to a parallel dimension through a black hole.

BMX champion and 2018 Youth Olympic medalist Iñaki Mazza retired from his sport during a period of personal crisis. Years later, he returns to his bike, emboldened by a new quest, and reunites with his partner after their stint at a rehabilitation center in Tierra del Fuego. Mazza sets out on a 3,000-kilometer trek in a cinematic portrait that blends formats, pairing underground BMX footage with beautifully expansive vistas at the end of the world.
