The one-hour program delivers an in-depth look at just how mainstream illegal gambling has become. From sports betting to online casinos to high-stakes poker, a high percentage of the betting is placed illegally. Interviews with "Paul," an illegal sports bookmaker who knows each bet he takes can land him in jail; professional gambler "Vegas Runner" who takes his job as a gambler as serious as any Wall Street trader takes his job; and the dangerous case of Nick Sarillo, a restaurant owner who freelances as a bookie, crosses the Mob and pays a heavy price; shed light on this lucrative, but risky activity.
