1781, Vienna. Court composer Antonio Salieri believes that Mozart's music is divine. He wishes he was himself as good a musician as Mozart so that he can praise the Lord through composing. But he is unable to understand why God favored Mozart who is such a vulgar, bawdy and impish creature, to be his instrument. Salieri goes mad with envy and has made himself an enemy of God. He is set to take revenge and plots to destroy Mozart by any means necessary.
