Illegal Gambling

S1, E4: Millions of Americans love to gamble. But some forms of gambling are restricted or illegal, pushing it underground, where the rules are very different. Here if you want to play you have to pay. The bookie will extend credit, but "miss a week, you miss a finger." Or worse. In the shadows of the law, people will bet on anything; legal or illegal. Innocent lives are put at risk in a world where only one thing matters--money.
