Taken under the wing of local gold lord Antoine Serra, Vincent quickly falls into the much more lucrative and dangerous world of gold trafficking. From Serra, who acts like a father to him, Vincent learns everything there is to know about the business. Newcomers aren't welcome - Louis, Serra's right hand, makes it clear that he does not trust him.

And things get even more complicated when Vincent discovers that the mythical Sarah Bernhard mine is not a legend. The Guyanese jungle is a world where businessmen, gangsters, geologists and soldiers collide, and men kill and are killed for a few grams of the precious metal.
