Blood River Crossing

In the most brutal migration on the planet, ride shotgun with ZuluEchoFive and FoxtrotOne, a zebra mother and her son. They run the gauntlet through crocodile infested rivers and lion offensives, culminating in the world's ultimate ambush: the Mara River - where the biggest crocodiles in Africa are on the attack.
