Chorus girls Polly, Carol and Trixie are ecstatic when they learn that Broadway producer Barney Hopkins is putting on a new show. He promises all of the girls parts in the new show and even hires their neighbor Brad Roberts, an unknown composer, to write some of the music. There's only one problem: he doesn't have the money to bankroll it all. That problem is solved when Brad turns out to be quite rich but he insists that he not perform. When opening night comes, the juvenile lead can't go on forcing Brad to take the stage. He's recognized of course and his upper crust family wants him to quit. When he refuses, they tell him to end his relationship with Polly or face having his income cut off. When Brad's snobbish brother Lawrence mistakes Carol for Polly, the girls decide to have a bit of fun and teach him a lesson.。1960年代,美国的广告业步入全盛时代,位于曼哈顿的麦迪逊大道有数百家广告公司,斯特林·库帕公司堪称行业中的佼佼者。创意总监唐·德雷柏(乔·哈姆 Jon Hamm 饰)面容英俊,体格健硕,足智多谋,仿佛广告业中的007。除此,公司中还有酷爱炫耀其上流社会出生的老板罗杰·斯特林(约翰·斯拉特里 John Slattery 饰)、识时务的秘书佩吉·奥尔森(伊丽莎白·莫斯 Elisabeth Moss 饰)、野心勃勃却缺乏真才实学的拜特·坎贝尔(文森特·卡塞瑟 Vincent Kartheiser 饰)等各色人等,他们一边为了满足客户的要求殚精竭虑,一边又要在生活的困顿中挣扎。。
