埃利诺·鲍威尔

唐纳（弗雷德·阿斯泰尔 Fred Astaire 饰）和肖恩（乔治·墨菲 George Murphy 饰）是一对跳双人踢踏舞的搭档。唐纳是一个佛系的舞者，对名利看得很淡，但肖恩和他恰恰相反，爱慕虚荣的他总想着有朝一日能够功成名就。一天，百老汇的经纪人凯斯（弗兰克·摩根 Frank Morgan 饰）在唐纳的身上看到了无限的星途，于是将他推荐给了歌剧院老板波斯（伊恩·亨特 Ian Hunter 饰），唐纳知道自己的搭档肖恩出名心切，于是将这个千载难逢的好机会让给了他。 　　果不其然，肖恩在舞台上一炮而红，很快就成为了闪亮的新星，但肖恩却似乎并不珍惜自己的成功，将时间和精力都挥霍在女人和酒精上。
