I'm in the co-pilot seat of the small Cessna plane and we're circling the Bolivian

Amazon.

Beside me pilot sweating because we're looking for a place to land and we can't find one.

The weather was bad and the pilot was nervous and it was quite exciting.

Behind me is this guy just been a day ago.

This German cacao hunter named Volker Lehmann.

Volker looks a bit like the German director Werner Herzog.

Sounds like him too.

The more dangerous or tricky the situation gets, the calmer I get.

It's 2010 and Volker's letting me tag along if he searches for a holy grail.

Volker cow, the tree that gives us chocolate.

The cow is native to the Amazon and now it's farmed all over the tropics, mostly in Africa.

A few years before our trip, Volker stumbled upon an incredible variety of wild cacao in Bolivia

and he turned it into this mind-blowing chocolate.

So now there's a gold rush for these magic beans.

And Volker's hope is to stay one step ahead.

There's an indigenous group in the forest on the Europe array.

Rumor has it that they have a ton of wild cacao to sell.

So the plan is, fly in, find a landing strip, take a dug out canoe to the Europe array village, strike a deal.

Below is the jungle looks, otherworldly.

The whole thing is steaming, mist rising to form these men's thunderheads.

And the thunderheads are dropping ropes black rain back to the forest.
