Meet Sudan, the last male of his sub-species, the Northern White Rhinoceros. NATURE: The Last Rhino (PBS Distribution) tells his harrowing journey through the international cast of characters who have been involved in Sudan’s life, from when he was snatched as a calf from his mother’s side in war-torn Central Africa, to his captivity as a prized exhibit in a cold, concrete zoo behind the Iron Curtain while poaching devastated his kind to extinction back home.

Now at 43 years old and half-blind, Sudan is living out his days under 24-hour armed guard, on a protective sanctuary in Kenya. As his kind nears its last hour, scientists and animal experts turn to technology in a race to save the Northern White Rhino before it dies out forever.
