It was a perfectly sunny L.A. afternoon, a charming curb-side restaurant right there in the sweet spot of the Sunset strip, lunch with a couple of members of an extremely exclusive club.
And one of them popped up and was across the place — and back — before I quite understood what was up.
"______," she told me, sitting down again. "He was the guy in the Paris video..." THAT Paris video.
A friend of hers, apparently. Or was he? As we had been discovering, the tight little world inhabited by the people who show up week after week on the covers of tabloid magazines is not quite the bright wonderland lots of us like to imagine.
Behind those velvet ropes, our lunch companions told us, it's a sometimes dangerous world, inhabited not just by the famous or the wanna-be famous, but by dark characters, bottom feeders and bad boys intent on making use of those very faces you see on the tabloids.
Our purpose, when we started, was to look into a terrifying home invasion robbery way up in the nosebleed section of Bel Air. I mean, way up. Nancy Reagan's neighborhood. Homes so expensive you can't even see them, in there behind their hand built gates, up their hedge-lined private driveways.Â
The victim of this robbery is a celebrity himself:Â Joe Francis, the man behind a ridiculously profitable moral quagmire called "Girls Gone Wild."Â Joe has been flogging his videos - college girls lifting their tops for the camera, playing sex games with each other, etc, etc - long enough to have built a boy's dream of a lifestyle.Â
Here is a partial list of Joe's toys:Â private jets (two), Bentley, Ferrari, the really nice house, other big house across the country, a place in the Caribbean.... and... friendships with people who are famous.
Like Paris Hilton. Who says, the second Joe's name comes up, "He's NOT my ex-boyfriend."
But did she know who got into his house one night, tied him up, threatened to kill him, forced him to make a video apparently aimed at making him look gay?
And thus, from our curiosity about a robbery, we found ourselves drawn into the bizarre world of Hollywood night life.
We listened to Paris call herself "like, not that smart." We heard her memory improve remarkably... after a sandwich.
What's it like behind those Hollywood velvet ropes?
Next time you find yourself in a check-out line and your eye is drawn to some ultra-famous party girl — or boy — splashed on a tabloid cover and you wonder, just for a second, how cool it must be to live in that world... you might remember this simple definition of celebrity life, from an L.A. County prosecutor named Hoon Chun: "Its a jet-set version of high school."
The Paris Hilton tapes previously aired on Dateline in September of 2006. An update of the report is supposed to air this Sunday, March 4, 7 p.m.

Meet a the guy who thinks he's about to get away it, at least for a few minutes. Mohamed Abdalla walks into our hidden camera house oozing with confidence. Notice how relaxed he is talking with our actress posing as a young teen home alone. Even when I walk out to talk to him, he's got his story all set and he's sticking to it.
This week, two strange soap operas attracted an audience of millions. On TV, on the Internet, and in print, the sagas played out. And depending on how you see all this, you can choose your own storyline -- women gone wrong, women done wrong, or girls gone wild.

After every 'To Catch the Predator' broadcast, the Dateline inbox always gets this question from viewers: Where are the female predators?
Hong Kong was lit up like an X-Box game on double espresso. Green lasers slashing the skyscrapers Kowloon side, red and gold beams rippling off Victoria Harbour. Driving in, craning our necks like hicks from the sticks, looking straight up the facade of the Bank of China cross-hatched with bars of light for umpty-ump stories. 
He kept chatting with the decoy though, who now told him she was visiting friends in Long Beach. Perhaps because he'd been caught by PJ before, Sierras wanted to meet our decoy at a park near our Long Beach house. We scrambled to set up cameras in and around the park and get our decoy in position. According to the chat log, Sierras discussed driving the girl home – all the way from Long Beach back to northern California, offering to take her to Disneyland along the way. 
I covered a plane crash years ago. The scene was horrendous but I did my best to block out my emotions and to report the facts in an accurate professional way. My dad was watching and later said something that was as close as he gets to advice. "Remember there were people on that plane," he said. "People with families."Â
