Premise: Each year the U.S. economy is flush with more than $500 billion generated in illegal transactions. From sex, weapons and drugs to gambling and counterfeit merchandise, nothing is off limits and seemingly everything is for sale. In ``Underworld, Inc.,'' National Geographic Channel is granted unprecedented access to this ``free'' enterprise. Workers, suppliers, sellers, customers -- and law enforcement personnel trying to keep it in check -- share their experiences of an underground industry that is brutal, exploitive and corrupt.
