Prisoners of Paradise
The West has always sought a paradise in the East. Conrad, Robert Louis
Stevenson, Gauguin and Margaret Mead all contributed to the myth of a paradise to be found in the South Seas.
Somewhere, there had to be a paradise on earth where beautiful people could live sensual but uncomplicated lives, where 'coming of age' was a time of casual courtship and not a time of stress. It was to be a place where there was little guilt and few inhibitions - a dream life under the palm trees.
Samoa became the focus for this dream.
But does the myth live up to reality? If Samoa is paradise, why does it have its fair share of violence - and the highest suicide rate in the world? This programme explores this 'paradise'.

A film about the great American artist and naturalist
John James Audubon who was born 200 years ago today, written and narrated by David Attenborough The voice of Audubon Olivier Pierre with John Ringham
Musicians SONG OF THE WOOD
In February 1984 a single set of the most spectacular bird pictures ever produced was sold in London for
£1,000,000. The revolutionary Birds of America was the triumph of one man's will over every discouragement. It celebrates the many years Audubon spent travelling across pioneer America, observing and drawing the wildlife. In Britain he found artists who could reproduce his designs to his exacting standards, and today a new edition of six of the original plates is also being printed.
