Three episodes of Louis Theroux's documentary series, where the deceptively baffled Englishman investigates some of America's strangest subcultures and meets some bizarre people along the way. In 'Gangsta Rap', Louis looks more out of place than usual amongst the gun-toting rappers of the American South. In 'UFOs', Louis joins up with some UFO believers and even manages to sneak into Area 51, but is that garbled recorded message really from the planet Koldas? In the bonus episode 'When Louis Met Jimmy', Louis spends some time with the eccentric DJ and presenter Jimmy Saville, and tries to find out what makes him tick. With his wardrobe full of his dead mother's clothes, his tall tales and prickly nature, Louis reveals a previously hidden side to the enigma that is Jimmy Saville.
