第四季将视野拓展到教育系统,其它主要情节还有第三季中引入的市长竞选,并深入描写了Marlo Stanfield领导的贩毒团伙在西巴尔的摩的不断壮大。In the Season Four premiere, four boys from West Baltimore play out their summer vacation in the streets. Meanwhile, Marlo has solved the problem that baffled Stringer Bell: how to maintain discipline--read: murders--without getting police attention.
