Mientras el desierto del Kalahari afronta una estación seca cada vez más larga, las diversas manadas y clanes deben apoyarse en el poder de la familia para sobrevivir.

Surrounded by the unforgiving Kalahari Desert, the Okavango Delta is a lush, vibrant oasis that pulses with life each year as the great flood rejuvenates the land with the return of water. Witness how incredible animals – like leopards, elephants, lions, hippos and more – adapt to this unpredictable and changing landscape. When the lands are flooded, the Okavango Delta is both a sanctuary and a trap, giving and taking life in equal measure. Then, like a living, breathing ecosystem, the waters soon recede and life becomes about one thing – survival. The fate of the tens of thousands of animals that live in this place of spectacular natural drama is at stake.

In southern Africa, a pride of lions has rewritten the rules - by learning to take down elephants. In this follow up to Africa's Giant Killers, we join the pride at the start of the rainy season. As the elephants depart, a catalogue of dramatic events unfolds. The pride males turn against each other, an inexperienced mum puts her newborn cubs in mortal danger, a rival group of lions challenge the pride for its territory and, when lightning strikes, fires burn day and night. When the dust eventually settles, the pride is left with only one choice - to face their old foe the elephants or risk starvation. The final showdown awaits.

The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.
