<p> 杰克•拉莫塔（罗伯特•德尼罗 Robert De Niro 饰）出身于纽约的布鲁克林区。自小便进行拳击训练的杰克很快就在拳击界崭露头角，他因在比赛中出拳迅猛，打击对手毫不留情，表现得就像一头公牛，被称为“愤怒的公牛”。

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 虽然杰克表现出色，但因为他为人耿直，不肯屈服于黑手党的安排，所以在当时他一直无缘于挑战拳王金腰带。在多次失意后，杰克终于向黑手党屈服，听从安排输掉了一场比赛。之后杰克如愿挑战了拳王并顺利加冕。
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 加冕后的杰克不仅没有体会到预想中的兴奋，反而看透了拳击界的种种黑幕，决意退出。</p>
