What happens back stage of a big theatre production? This document asserts the incidents that occurred during the rehearsals and run of a big scale Mexican musical, a show that unexpectedly turned into an attempt to verify that famous quote that said "the show must go on": laugh, tears, victory, deception, friendship and resignation.

A story about the meeting between surrealist film director Federico Fellini and writer Carlos Castaneda, an anthropologist and apprentice shaman. Fellini goes looking for magical Mexico together with Castaneda. The journey confronts him with himself and he is pursued by voices, strange occurrences, meetings and reunions that defy the passage through space time; inexplicable coincidences that fascinate, irritate and intrigue him. Crossing Mexico from north to south shows the many facets of the country, the varied landscapes and realities of the territory. He and his travel companions are at the same time witnesses, victims and protagonists of a surreal adventure that takes them from Tijuana to Tulum.
