Rent Gerald Durrell: To the Island of Aye-Aye (1991)

Bridges that nearly collapsed as they were crossed and ancient ferries which ran a 'sometime-this-week' schedule, were just a couple of the problems which Gerald and Lee Durrell faced on their expedition in Madagascar. They were looking for one of the world's rarest creatures, the Aye-Aye. The plan was to set up a captive-breeding programme in a bid to save this strange species of lemur from following the Dodo into extinction. After weeks of trekking through the rainforest without seeing any Aye-Aye the local witch-doctor was called in to help but first he had to talk to his ancestors.
