Steve Backshall leads a team of elite explorers - including world leading underwater cave explorer Robbie Schmittner, former Royal Marine Aldo Kane and diving camera operator Katy Fraser - into the wilds of the Yucatan Peninsula in Mexico. Under the vast jungle here is the largest unexplored network of caves in the world, comprising thousands of kilometres of passageways. They are stunningly beautiful but incredibly dangerous - much of the system is under water. First the team must trek through tough, scorpion-infested jungle to camp alongside a giant sinkhole in the jungle floor - a dark gateway to an underworld full of nightmarish creatures.

In the thick of the jungle of Rwanda's Volcanoes National Park, an infant mountain gorilla has been caught in a snare. If the rope is not removed quickly enough, the young gorilla could lose its hand. In order to remove the snare, a team of veterinarians will first need to sedate the infant's mother. But if the infant screams too much, the three 400-pound adult males that form part of this gorilla group will all attack. Everything must go perfectly, or there's no telling what could happen. And being jungle medicine, things rarely go perfectly. The pioneering group of vets performing this medical intervention is known as Gorilla Doctors. Led by Canadian Mike Cranfield, they work in Rwanda, the Democratic Republic of Congo and Uganda, where the world's last Mountain Gorillas can be found.

On a high ridge in Newfoundland, Canada, nestled between the Atlantic Ocean and the borders of an old grove forest, a Red fox, the matron of her family group, gives birth yet again. Follow the pups as they grow and learn to hunt, adapt, and survive. Explore the family dynamic of these clever creatures as bonds are formed. But the vixen knows that not all her cubs will inherit these tall trees, crystal lakes, and the ocean spray. Before the snows come again, she will have to banish some of her offspring for the good of the family. We also hear from scientists in Madison, Wisconsin and Bristol, England, about their studies on urban Red foxes who are facing a much different challenge than their Canadian counterparts. And another scientist tracks how Red foxes are moving out to the Arctic tundra and surviving in one of the harshest landscapes.

In the second of this two-part series, Colin Stafford-Johnson continues his journey in Cuba, one of the most captivating islands in the world. Here, he encounters bats emerging from a labyrinth of limestone caves to feed on nectar from giant hibiscus flowers, and tiny frogs, smaller than a fingernail, living in patches of hidden emerald forest. And on the white sand beaches, baby green turtles emerge from their nests to make their way to the sparkling Caribbean Sea.
