Deep in the equatorial heart of the remote Congo Basin lives a tiny colony of gorillas. These are the last survivors of earth's largest primate species. Until now, these wonderful animals have lived a quiet, secret life away from people. But with human development on the horizon, the race is now on to ensure that Congo’s gorillas have a permanent home in the future.

Chloe Cipoletta has dedicated her life to study and protect them. This is the extraordinary tale of her struggle to help them acclimatise to eco-tourism in a last-bid attempt to preserve their kind.

Chloe’s solution is radical, yet simple: she wants to habituate a family of gorillas to human contact. If she succeeds, then a whole new tourist industry will be born, as well as a good financial reason to protect the forest home of one of humankind’s closest relations.
