本片从一个宫廷乐师萨里埃利的角度，为我们呈现了天才莫扎特的一生。萨里埃利（F·莫里·亚伯拉罕 F. Murray Abraham饰）是维也纳音乐界里有名的人物，自视甚高的他自从遇到了莫扎特（汤姆·休斯克 Tom Hulce饰），心里的妒嫉之火便熊熊燃烧不能平息。莫扎特总能以他超乎常人的音乐作品赢得全场惊叹，他的《费加罗的婚礼》等歌剧，都成了传颂千古的经典。 　　萨里埃利对莫扎特又羡慕又嫉恨的心理已经发展到几乎扭曲的地步。他在莫扎特的事业上一次次的从中作梗——故意缩短歌剧的上演周期，恶意删改莫扎特的作品，在莫扎特承受着丧父之痛时给他无情的精神折磨。贫穷虚弱的莫扎特在生命最后的几年里，写就遗作《安魂曲》，一代大师35岁就与世长辞，留下不朽作品。而萨里埃利，早有等待他的宿命般的结局。Antonio Salieri believes that Wolfgang Amadeus Mozart's music is divine and miraculous. He wishes he was himself as good a musician as Mozart so that he can praise the Lord through composing. He began his career as a devout man who believes his success and talent as a composer are God's rewards for his piety. He's also content as the respected, financially well-off, court composer of Austrian Emperor Joseph II. But he's shocked to learn that Mozart is such a vulgar creature, and can't understand why God favored Mozart to be his instrument. Salieri's envy has made him an enemy of God whose greatness was evident in Mozart. He is ready to take revenge against God and Mozart for his own musical mediocrity.
