Mardi Gras (S06E10)

Mardi Gras means two months of crazy carnivals leading to one of the biggest parties in the nation. But as tourists flood New Orleans, so do drugs dealers eager to make a profit. Mardi Gras is the busiest time for those in the drug trade — the demand doubles, making the chance for profit too great for dealers to resist. The DEA cracks down, disrupting the drug trade. Local law enforcement looks to protect visitors and keep the city safe, but dealers engage in a fierce competition. When one dealer tries to boost profits by selling fake drugs, he finds himself to be the target of other dealers. (National Geographic)
