LIVING WITH WILD LIONS, ON THE PREMIERE OF "PRIMETIME: THE OUTSIDERS," TUESDAY, AUGUST 11

Lions may be the kings and queens of the African bush, but their kingdom is fast disappearing. And two extraordinary men, in two extraordinary ways, are breaking all the rules to try to save the lions. Kevin Richardson is an affable South African known as the �Lion Whisperer,' whose affection-based training methods have enabled him to become an honorary member of a pride he raised at his wildlife park. He interacts with the lions in an intimate way that has never been seen before, but that does not protect him from the aggressive traits that cause lions to turn on him and attack at a moment's notice. And hundreds of miles away in the bushland of Namibia, Animal Planet host and big cat trainer Dave Salmoni is risking his life trying to rehabilitate a pride of wild lions so dangerous that they were earmarked for destruction at a national park. In an audacious attempt to save them, Dave convinced the owner of the Erindi Game Sanctuary to let him teach the aggressive pride of lions how to calmly live among the eco-tourists that support the park. But is it worth risking his life?

Jay Schadler travels to Africa to report on the unforgettable journey of two men living with lions, both of whom are challenging the boundaries of the natural world and, ultimately, what it means to be human. Schadler's report airs on the premiere of "Primetime: The Outsiders," TUESDAY, AUGUST 11 (10:00-11:00 p.m., ET) on the ABC Television Network.
