Cokeland (S05E02)

Oakland, Calif., has been rocked by a police corruption scandal and a $58 million budget deficit that have decimated the city's police department staffing and morale. The drug market has become an unregulated free for all, worth millions of dollars per year. NGC follows an elite team of detectives working around the clock to bring down the ringleaders. And access to the dealers, users and gang members at the heart of it all provide an unforgiving look inside the crack- and cocaine-infested city. (National Geographic)
