In the heart of Africa, straddling the borders of Rwanda, Uganda and Congo, lies a remarkable mountain kingdom. It's home to the last 700 mountain gorillas in the world. With so few left, they're under constant surveillance from a dedicated band of humans.
Our cameras have been given privileged access to these precious animals by the people that record every detail of their lives.
In this programme, we'll be following some of the youngest and most vulnerable gorillas. We witness the plight of two orphans caught in a brutal civil war. A young female on the cusp of adulthood, battling with feelings she's unable to control. And a new gorilla king, struggling to earn the respect of the group he fought so hard to win.
