Reveals Mexico's astonishing wildlife, landscape and culture in three distinct worlds - great mountain ranges, tropical forests and scorching deserts.

Ch1. Mountain Worlds
Mexico is a vast country, over 2,000 miles long, dominated by a great chain of mountains, the Sierra Madre. Journey down this rocky spine and discover an amazing diversity of life, from black bears and orchid bees to resplendent quetzals and millions of monarch butterflies. This is a land where giant volcanoes simmer and ancient and modern cultures collide in a festival of life.

Ch2. Forests of the Maya
The ancient temples of the Maya still tower over the forests of the Yucatan, where jaguars, monkeys and vibrant tropical birds now make their home. It's a forest full of secrets, with a vast watery underworld that is still being explored and which holds the key to how animals and people survive the dry season.

Ch3. Burning North
Northern Mexico is the country's driest region, dominated by two great deserts; the Sonoran and Chihuahuan. And as you travel west the conditions get hotter, drier and more challenging. In this film we unravel the forces that have created this arid world and discover that for the animals who live here, from prairie dog and pygmy owls to rare aplomado falcons, overcoming these conditions can bring rich rewards.
