A thousand elephants, from magnificent bulls to vulnerable orphans, come together in a crucial annual gathering in northern Kenya, whilst facing deadly threats from both predators and poachers.
Liz Bonnin leads a team of scientists and film-makers using cutting-edge satellitetracking technology to follow individual elephants day by day as they cope with their daily challenges.
The team capture surprising new behaviour and witness how elephant society is responding to a world changed by poaching, including the remarkable way young elephants are coping with the loss of their parents.
