Amid the chaos of war-torn Rwanda, anthropologist Pascale Sicotte has risked her life to protect one of the world's last remaining populations of mountain gorillas from poachers and loss of habitat.

In dangerous surroundings, she carries on work started by the legendary Dian Fossey, guarding the sanctuary of more than 100 mountain gorillas--and convincing the Rwandan government that, thanks to ecotourism, the precious primates are worth more alive than dead.
