Montalban is a musician trapped in an unfinished opus. As a boy he witnessed the death of his sister who was murdered on top of a piano, accidentally composing the melody as she did so. Eliseo Montalbán becomes an obsessed, mentally disturbed musician, trapped by that melody – the composer of a lethal, avant-garde, coveted musical piece. Years later, another man attempts to rescue that original symphony, without being aware of the dangers involved in doing so. Ricardo Coppa is a mediocre, talentless musician seeking recognition and success; an all-time Salieri. Together with a group of musicians, he embarks on a journey to look for Montalbán and his own composition.
