"The illegal, multibillion-dollar global sex trade includes brothels, massage parlors and online escort agencies and is one of the oldest professions. Take a look inside this illegal trade where pimps treat women as commodities \u2014 bought and sold, used and abused, then discarded."

"Mexican cartels dominate an extremely lucrative industry exporting undocumented migrants and squeezing them for cash. Thousands of Central Americans head north to the US border, lured by hopes for a brighter future, but people smugglers, who are often linked to cartels, make it difficult to cross without their supervision, and for a price."

"Millions of Americans love to gamble, but some forms of gambling are restricted or illegal, pushing them underground, where the rules are very different. Here, if you want to play you have to pay."

"Knock off Pharma is on the internet, in the pharmacies and on the streets. The trade is getting ugly and the consequences are deadly."

"Black market moonshine is big business \u2014 high-proof, low-cost, untaxed and illegal. But the law is cracking down and urban bootleggers are bringing fresh competition. It\u2019s the first day of the whiskey-making season for one expert moonshiner. Rosco needs two key elements for a successful and lucrative operation \u2014 secrecy and water. He\u2019s found the perfect hidden site deep in the traditional heart of moonshine production: the southern Appalachian Mountains. But 700 miles southwest, in Holmes County, Mississippi, there\u2019s a special police unit cracking down on \u2019shiners like Rosco."

"Increased automobile security means that car criminals are becoming more ingenious than ever. Gangs are working together to steal cars \u2014 for them car theft can be more profitable than selling drugs. In Santa Maria, California, three cars are stolen every day and police are now targeting the thieves rather than recovering vehicles. The criminals, meanwhile, rush to get the cars out of state, and then \u2014 via corrupt shippers \u2014 overseas. In West Africa, a criminal class has arisen that is willing to pay top dollar for high-end stolen U.S. cars."

"In America, 14 people die each day waiting for a kidney transplant. Meanwhile, the black market organ trade is thriving, and gangsters with global reach are pocketing easy money.

"Underworld Inc. follows the dirty drug dollars from American trap houses to wholesalers and transporters, funnelling billions into Mexico\u2019s money laundry. US authorities are closing in on cartel cash. If drug lords want their narco cheddar cleaned and moved into the banking system, they have to get it to Mexico. Working to stem the tide, the cops hit stash houses, and interdiction teams tail cars suspected of smuggling millions. South of the border, launderers use money changers to turn drug profits to pesos for onward investment in front companies and bogus construction projects. If local authorities pry into these shady businesses, they get warned off \u2013 cartel style."

"In Williston, North Dakota, an oil mining boom has brought tens of thousands of blue-collar workers to this once sleepy town. But the 21st century \u2018black gold rush\u2019 has also attracted black market operators into town. Motorcycle gangs extort Williston\u2019s bars and strip clubs, while pimps net millions from prostitution. But with the oil boom going bust, criminals must adapt. Laid-off oil workers are becoming this underworld\u2019s most resourceful criminals. Fueling the problem: drugs. Meth-related crime is up 78%. Williston\u2019s law-breaking is now migrating to nearby Fort Berthold Tribal Reservation, where a 12-man police department is inheriting crime brought by 4,000 non-native Americans onto their land from the oil field."

"From card cheats, to armed robbers, criminals across America make a beeline for the Casinos of Las Vegas. To defend themselves casinos have become crime fighting organizations.
