A week before Easter a great actor, called "The Maestro" disappears from the set which he had secretly organized to shoot an historical film. A detective is discreetly instructed to investigate his fate. A strange feeling envelops the fact from the very first investigation jokes. The detective indeed goes through the disquieting feeling of being somehow involved in the events spent of the actor, who lived in a former chocolate factory where years before a child was drowned in the adjacent waterfall. Several esoteric signs suggest that a dark world envelops the mystery. The Man, in the spasmodic yearning of omnipotence, clashes with the proud reaction of the Nature (the Woman), not at all willing to accept his domain.
