Bear Grylls ventures into the landlocked country of Zambia in Southern Africa. Before heading into the bush, he shows you how to survive some of the world's biggest rapids. Flashfloods mean the Zambezi River is bursting at the banks and in the Batoka gorge 12 ft waves and vicious currents regularly claim the lives of canoeists and rafters. Armed with a body board, Bear drops into the heaving waters and manages to make it to shore. With a healthy population of crocs and hippos, commonly thought to be Africa's most dangerous animal, in the river, he needs to climb a sheer rock face to get to the safety of the bush. And when a tree branch breaks, he nearly doesn't make it. Its rainy season in Zambia and Bear amazingly comes face to face with 80 elephants. A nearby leopard kill means food for Bear, but unfortunately it's not long before Bear suffers from diarrhea. Coupled with the heat and humidity of the African bush, he struggles to make it out but, as always, he has plenty of ingenious survival strategies ready to face any impending danger.
