Cyril Chauquet and his team are dropped into the middle of the wildest environments on the planet with the sole mission of collecting vital specimens that could save species from extinction. After years of habitat destruction, pollution and commercial pressure, Chauquet and his team are on tight deadlines to make it through the dangerous rugged terrain and back to civilization. The teams seek out some of the most endangered freshwater goliaths from the Great North of the Americas and the Amazon rainforest, including the armor-plated white sturgeon, the prehistoric pirarucu and the hulking piraiba.

Lurking in the murky depths of the world's great waterways are bizarre giants - specimens of such enormous proportions and odd appearance they boggle the mind. Remarkable freshwater fish that can reach astonishing lengths of 3.5 metres, weigh a scale-busting 200 kilograms and carry heavy suits of scaly armour. Some breathe air and are even rumoured to prey on people! Other aquatic giants have survived since the dinosaurs but now are dwindling in numbers and face an all-too-real threat of extinction.
