Een uitgebluste reddingsduiker krijgt nog één klus voor zijn kiezen: zijn vrienden redden van een monsterlijke megalodon, waarvan men lang dacht dat hij was uitgestorven.

David Attenborough returns to the island of Madagascar on a very personal quest. In 1960 he visited the island to film one of his first ever wildlife series, Zoo Quest. Whilst he was there, he acquired a giant egg. It was the egg of an extinct bird known as the 'elephant bird' - the largest bird that ever lived. It has been one of his most treasured possessions ever since. Fifty years older, he now returns to the island to find out more about this amazing creature and to see how the island has changed. Could the elephant bird's fate provide lessons that may help protect Madagascar's remaining wildlife? Using Zoo Quest archive and specially shot location footage, this film follows David as he revisits scenes from his youth and meets people at the front line of wildlife protection. On his return, scientists at Oxford University are able to reveal for the first time how old David's egg actually is - and what that might tell us about the legendary elephant bird.

A trio of experts venture into Tasmania's undeveloped wilderness in search of the Tasmanian Tiger, one of the most terrifying predators ever to walk the earth.

Recorded by pioneers as far back as 1805, the Tasmanian tiger has become an intensely mystifying Australian icon, whose entire existence has become the stuff of both fable and legend. This program investigates a chequered past and puts the speculation into perspective, taking into account the tragic culling and ‘bounty era’ where the carnivorous creatures were thought to be solely responsible for a considerable loss of farmers’ livestock. Balancing the facts with personal reflections from Tasmanian locals, scientists and other informed practitioners, The Tasmanian Tiger is a thought-provoking and revealing look at the extraordinary life and death of one of Australia’s most mysterious marsupials.

There are about 250 people with a unique ancestry. Livonians – one of the smallest and most endangered nations. Each of Livonians has a duty to preserve their identity and the great history of their ancestors. Trillium follows the footsteps of a poet and researcher Valts Ernštreits, who is one of 20 people able to speak fluent Livonian – an indigenous language related to Estonian and Finnish – in his efforts to look after the language and culture of these ancient settlers of the Baltic Sea coast.
