Vincent Ogier, a twenty years old Parisian geology student, landed in Guyana for an internship at a gold mining company: Cayenor.An immoderate taste for danger will push Vincent to associate with the "godfather of gold" Antoine Serra, who reigns over the village of Saint Elias. Vincent believes he has found a mythical gold mine: a mine abandoned for 120 years, named "Sarah Bernhardt"... Serra has the skills required to operate it. Seemingly paternal and friendly, Serra accepts and embarks Vincent in the depths of the Guyanese jungle...Within a few weeks, Vincent will pass from the status of intern to that of adventurer.
