约克郡公爵阿尔伯特（科林·费斯饰）有一个致命的缺陷，那就是令人心烦的口吃病，这让他无法在公众面前发表演讲，连续在大型仪式上的出丑让他有些心灰意冷，对政治前途开始淡漠起来，幸好他有一个非常贤惠的妻子伊丽莎白（海伦娜·邦汉·卡特饰），为了治好丈夫的口吃，她不惜辛苦四处求医，可始终没有效果，连阿尔伯特都失去了信心

在一个偶然的机会中，她听说语言治疗师莱纳尔罗格（杰弗里·拉什饰）对纠正口吃有着不错的效果，于是慕名前来拜访，可是阿尔伯特却对莱纳尔罗格稀奇古怪的招法很不耐烦，第一次的诊疗以不欢而散而告终，回去之后，阿尔伯特无意间发现自己在听音乐时朗读莎翁的著作竟然非常流利，这个变化让他开始对罗格的治疗有了兴趣，在他积极的配合下，效果十分明显，他也慢慢克服了心理障碍，自如地跟大家进行交流了。由于乔治五世驾崩，阿尔伯特临危受命成了乔治六世，眼下就有一个难题考验着他，在二战前发表鼓舞人心的演讲是当前的重中之重。
