Nature: Giraffes: Africa's Gentle Giants

Dr. Julian Fennessy has spent years studying giraffes. The population in Africa is down by 40 percent. Fennessy and a Ugandan Wildlife Authority team want to round up 20 of the world's rarest giraffes to get them to safety. The stakes are high in this urgent and daring mission against poachers affiliated with organized crime, but if successful, the reward will be a brighter future for the giraffes.
