Underworld, Inc. - Season 2 Episode 5

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. 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.
