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.。《重案组》作为《罪案终结者》的衍生剧,将接收不少原剧卡司并展开新故事:两次获得奥斯卡提名的玛丽·麦克唐纳(Mary McDonnell)将作为新女主Capt.
