Dian Fossey: Secrets in the Mist

Cries of horror cut through the early morning mist on a mountainside in Rwanda. Dian Fossey, one of the greatest names in wildlife conservation, is found dead, killed in a brutal machete attack.

Days after the slaughter of Dian Fossey's favourite gorilla, Digit, Sir David Attenborough arrives to find her coughing blood. She insists on taking him to film the gorillas in what becomes one of televisions most famous sequences.

Everyone who knew Dian Fossey is shocked by her murder, but not surprised, as she made many enemies. An inept police investigation provides few clues.
