《风骚律师》宣布续订第4季，长时间谈判后终于等来这消息了。根据该剧状况是不愁续订的，毕竟是AMC收视第三(次于《行尸走肉》《行尸之惧》)，但此前主创Vince Gilligan和Peter Gould与AMC就很多问题在谈判，有不确定因素。

故事紧接上季结尾，阿布奎基（Albuquerque）律师Jimmy McGill遭到哥哥Chuck的背叛，于是回到伊利诺伊州的家乡西塞罗（Cicero）与童年死党Marco（Mel Rodriguez）一起策划一系列诈骗诡计。他们成功了，但Marco在他们最后一次干脏活时突发心脏病。Marco死后，Jimmy回到了新墨西哥州，他的人生似乎有了新的意义。他拒绝了圣达菲（Santa Fe）一家大型律师事务所的工作邀请，朝着刑事辩护律师「Saul Goodman」的方向迈出了一大步，他「清白正直」的日子一去不返。他的转型……已然开始。但是制片人反复强调，你不会在本季看到一个完整的Saul Goodman，「Jimmy McGill才是该剧的灵魂人物」，「我们要描述的是他的故事」，「我们不会这么快和他道别」。
Jimmy本季有许多事情要做，包括修复与哥哥Chuck（Michael McKean）的关系。Chuck始终不相信Jimmy是一个合法的律师，并且阻止自己的Hamlin Hamlin & McGill律师事务所雇用Jimmy协助调查一起大案。Chuck是个荣誉感很强的人，他爱弟弟，但他不容许他破坏自己的事业和生活——即便有时他不得不承认自己的做法对Jimmy来说有点太过分。
观众将进一步了解Mike Ehrmantraut（Jonathan Banks）的个人生活。当费城侦探跑来向他质询一起双重谋杀案时，他被迫雇用Jimmy做自己的法律顾问。这起谋杀案是真实的，Mike当年为了复仇在费城杀死了两名警察，但他绝不是恶意杀人。Mike将发生一些显著的变化，但那些变化起源于小事情。
Jimmy和Mike都在朝着《Breaking Bad》中的标志性角色发展，这期间少不了许多「彩蛋」。本季还会有不少闪进情节，观众将看到「Saul在《Breaking Bad》结束后的生活」（准确地说，Cinnabon的Gene），还有「到目前为止最年轻的Jimmy」。一些观众在《Breaking Bad》首季中见过（但是之后再也未见到）的角色将在本季亮相。当然，还有观众熟悉的一些人。此外，Jimmy是个天生的「问题解决者」，他将帮助许多新角色摆脱困境。他还将遇到一个大人物Clifford（六届艾美奖提名获得者Ed Begley Jr.），他手中掌握的权力能让Jimmy诸多梦想变为现实……只要Jimmy付得起他的价钱。Clifford表面上看起来慈祥和蔼，让人很乐意和他待在一起。可一旦任何人触犯了他的利益，必将遭遇灭顶之灾。除了继续与Chuck关系紧张之外，Jimmy与Kim的矛盾也日渐升级（但是Jimmy与Kim的私人关系也变得更加纠缠不清）。你还应该特别留意Jimmy与Davis和Main的关系、Jimmy与Mike的关系。
