This was actually not filmed in a karaoke room.

That was a massive room where every wall and the ceiling was all a screen.

It was like the future.

And this is in a war-torn area of a country that's incredibly poor, and they've built this place with millions and billions of dollars from profits of scamming.

And we ended the night with this guy, who's basically the head of this criminal Chinese gang running these scams, in this karaoke singing Celine Dion and Whitney Houston.

And being poured whiskey and whatever high-end brand we wanted.

Oh, my God, yes.

I was singing my heart out.

I spent the whole night singing Whitney Houston.

The videos are so embarrassing because I cannot sing to save my life.

But I was like, well, we need to get this guy on tape, so I'm just going to do whatever.

And then the next day we interviewed him, and it was just fucking crazy.

And we ended our last day.

I mean, we interviewed a Chinese dude, so sad, like 21-year-old, who was caught trying to escape and was chased out of the building.

He ran out of a third floor, broke both his legs.

One at the hip, practically died, was actually saved by an onlooker who took him to the hospital and then moved to Thailand where I met him.

He was in a wheelchair.

Told us about beatings.

We spoke to another Indian kid also who was, they had a water hose on his body.

He was forced to stand for 24 hours and then electrocuted.
