THIS three-part series sees Patrick Stewart narrate a documentary following the last remaining members of a species of gorilla as they fight for survival in central Africa.

Just a handful of families cling to existence on the forested peaks of three isolated volcanoes in a small corner of Africa.

Cameras enter this fragile world to chart the life of one gorilla family as they go about their day-to-day existence.

The series explores the history of the mountain gorilla, from their discovery a century ago through their ongoing battle to survive.
