南高县一把手的位置空半年了，上上下下都以为这把交椅非副县长刘超莫属，刘超自己也做好了大展宏图的思想准备，可忽然间从上边派来一个吴书田，人们都觉得此人来头不小。其实硕士研究生吴书田没什么背景，不过是在面对社会公开选拨公务员时考入省委机关，因不谙机关世事，同领导意见相左，被贬了下来。这个书生气十足的吴书田却是个认真的人，尤其对本县已经司空见惯而熟视无睹的制假贩假活动，毫不妥协。这样一来便触动了以刘超为首的地方势力，他们以维持地方财政为名，凭借其经营多年的人事网络，给吴书田制造了一个又一个困难，他们为了掩盖罪行，撵走吴书田，夺回权利，不惜在吴书田与妻子虞雅之间挑拨事端，编造绯闻，甚至利用车祸杀人灭口。但改革开放毕竟是大势所趋，吴书田在农行女行长王宁、县委办公室主任赵亮等人的帮助下，终于战胜了盘根错节的地方势力，使南高县的工作走上了改革开放、健康发展的轨道。本剧生动细腻的塑造了一位新时代的县委书记的形象。

The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu
