Izzy Rossi receives a coded map, the last piece of her deceased father's research, supposedly leading to the legendary "City of the Serpent God," a lost city filled with untold riches and ancient artifacts. She hires Marco "Pantera" Almeida, a renowned local guide, to lead her through the treacherous, uncharted regions of the Amazon. She does not disclose the gold. Unbeknownst to Izzy, a ruthless mercenary group, led by Javier Vargas, is also after the treasure, funded by a corporation that wants to exploit the region's resources. They are tracking Izzy, using her as a pawn to lead them to the city. Marco knows more of the legend than he discloses. Early in the journey, Izzy and Marco find evidence that another expedition, one connected with historical colonizers, sought the same treasure centuries ago and met a terrible fate. They find ruins and traps.
