British journalist Louis Theroux travels to the Hilton Hotel of Las Vegas, Nevada to peak behind the curtain of the gambling industry that made Sin City famous. The Las Vegas Hilton is an important piece of the city’s history; Elvis Presley performed over eight hundred sold-out shows in the hotel’s casino during his lifetime. As Theroux uncovers the myths of casino culture, he meets the people that keep the industry lucrative.
Among them are two casino high-rollers (a.k.a. “Whales”), one of whom traveled from Canada and was prepared spend two hundred thousand dollars in a single weekend. Theroux also meets casino “super host” Richard Wilk who’s grown quite adept at saying yes to his clients. As he makes his way to the slot machines, Theroux meets Martha, a doctor who spends approximately a thousand dollars a day on the machines. Martha has been at the slots every day for ten years and has lost some four million dollars.
