Bertie travels to Botswana to film one of the planet's most successful land predators: the African wild dog. Despite their hunting super skills, wild dog population numbers are dramatically declining. By following a family pack with 14 young pups, he wants to find out what it will take for the next generation of these endangered predators to survive. They face threats from lions, hyenas and elephants, and it's clear that these African wild dogs don't go down without a fight.

Bertie is on a stakeout deep in the jungles of the Central African Republic, searching for the biggest and most secretive of the forest elephants: the tuskers, huge males with tusks that reach down to the floor. Working with a specialist camera team and local elephant trackers, he sets up a filming HQ high in the rainforest canopy.
