Gambling in Las Vegas

Louis Theroux heads to Las Vegas, the fastest growing city in America, to take a look at the pastime that made it famous and meet the gamblers, the high rollers and the casino men who keep this town in the middle of the desert green with money.

The Las Vegas Hilton is Louis's home over the course of one very memorable long weekend. Once the biggest hotel in the world, it is old school Vegas with a face-lift; this is the casino where Elvis played over eight hundred sold-out shows.

We meet Richard Wilk, the Hilton's smooth-talking 'super host' who prides himself on his ability to say yes to his clients. Louis hangs out with Richard's high-rolling 'whales'. Whales like Allan, who flies in from Canada to party in a 25,000 dollar suite, ready to blow 200,000 dollars or more over the weekend.

Louis makes his way past the dancing girls and flashing lights to find Martha, a glamorous septuagenarian who spends at least 1,000 dollars a day on the slots. She hasn't missed a day in ten years and has lost 4 million dollars.

And there's John and Tim, Vegas regulars who take Louis under their wing as he nervously gambles his own money on one long night on the black jack table. They walk away at 5am - but are they winners?
