Kenya's Amboseli National Park is a victim of its own success. It now has so many elephants that they are beginning to pose a threat to the local Maasai.

Meanwhile, elephant biologist Cynthia Moss is tackling the problem the park now faces: how do you save these famous elephants when they are intent on destroying their own home?
