People of the Poppy
To save itself from its own savage heroin addiction, the West has persuaded the East to attack the problem at source - the opium fields of Northern Thailand. In doing so, a traditional way of life for the ' People of the Poppy ' - the hill tribes of Thailand - is being destroyed.
This film looks at one of these tribes-the Meo, their traditional way of life, their dependence on opium as their only cash crop and the efforts being made by the King of Thailand and his Government with the help of the United Nations to introduce economic replacement crops, modern medicine and an education for a new life - a life without the poppy.
If and when the projects are successful the law of Thailand will be enforced. The poppy will go - and with it the rich cultures it sustained and shaped.

Variations on a theme of patterns, light, sound and music in a film without words.
An African sun dissolves the lingering lake-side mist revealing wraiths as hosts of feathered flowers - pink-tipped orchids poised on slender stalks. Myriad wings take flights of fancy, free as wind and sky, coming together in communion to reflect on golden sheen ... turning to silhouettes at sunset ... strung with Diane's diamond necklace at night. Birds of demi-paradise. Produced and photographed by Patrick Carey
