Africa 2013: Countdown to the Rains

Kate Humble and Simon King report from Zambia, following the lives of the animals living along the Luangwa River at a critical time in the seasons. There has been no rain for seven months and every animal, large and small, is locked in a struggle to survive - the elephant and her new born baby, the tiny lion cubs threatened by a power struggle in the pride and the hundreds of hippos and crocodiles squashed uncomfortably close as the river bed dries up. 75 cameras capture every moment as it happens through the last days of the longest dry season in memory to the arrival of the rains that will change everything.
