In the perilous depths of the Amazon jungle, Cyril and his team embark on a thrilling mission that pits them against armed poachers and fierce wildlife.

Their objective is to safeguard two of the largest freshwater fish on Earth: the heavily armored pirarucu and the enormous Piraiba. These elusive creatures are at risk due to human actions, and the crew must track them down to gather non-invasive DNA samples for scientists striving to ensure their survival, all while navigating the treacherous jungle environment.
