It really is a big bad world out there. So what happens if you are the little guy? This film tells the epic survival stories of the world's smallest animals.

To make a living, these tiny heroes have evolved extraordinary skills and achieved mind boggling feats. From the animal kingdom's greatest artist to the tiny creatures that provide us with so much of the air we breathe, we discover what it takes to be a miniature miracle.

The remarkable story of 43-year-old Sudan, the very last male northern white rhino on the planet. Aged just three, Sudan was snatched from his mother's side in Central Africa. He became a prized exhibit in azoo behind the Iron Curtain, while the rest of his kind was poached to extinction in the wild. Today, Sudan has become an unwitting celebrity and the focus of a desperate eleventh hour battle to save his sub-species. This astonishing modern day fable is told through the international cast of characters who have been involved in Sudan's life, for better and for worse.
