Louis Theroux's Weird Weekends - S1 E1

2. UFOs

Louis has a close encounter with the community of hardcore UFO believers in the South West of America - but not even an illicit foray into the ultra-top-secret Area 51 military base and a garbled message from the planet Koldas can answer all his questions.

3. Porn

Louis strips off and plunges into the world of Porn. From the glossy high-end productions to the sleazy "gonzo" flicks, he gets intimate with the men and women who bang for bucks. But is it all as fun as it seems? And what happens when you can't "get wood"?

4. Survivalists

Louis travels to the American North West, a place where survivalists, white separatists, and paranoid "freedom fighters" are arming themselves against the "New World Order". Meet the "radical nuts" and "noodles" who shoot first and ask questions later.
