Watch Underworld, Inc. Season 2 in Australia

Black market moonshine is big business — high-proof, low-cost, untaxed and illegal. But the law is cracking down and urban bootleggers are bringing fresh competition. It’s the first day of the whiskey-making season for one expert moonshiner. Rosco needs two key elements for a successful and lucrative operation — secrecy and water. He’s 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’s a special police unit cracking down on ’shiners like Rosco.

Increased automobile security means that car criminals are becoming more ingenious than ever. Gangs are working together to steal cars — 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 — via corrupt shippers — 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. Desperation drives this illegal trade in human spare parts, but the medical community is sounding the alarm and international law enforcement is in hot pursuit of the traffickers.

Underworld Inc. follows the dirty drug dollars from American trap houses to wholesalers and transporters, funnelling billions into Mexico’s 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 – 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 ‘black gold rush’ has also attracted black market operators into town. Motorcycle gangs extort Williston’s 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’s most resourceful criminals. Fueling the problem: drugs. Meth-related crime is up 78%. Williston’s 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.
