A simple DNA test which involves a swab in the mouth can reveal where your ancestors came from 30,000 years ago. In Made in Taiwan, molecular biology leaves the classroom as the two central characters, Nathan Rarere and Oscar Kightley, both of Polynesian descent take us on a journey across the Pacific and into Asia, in search of their roots. During the course of the film, Nathan who opens the envelope with the results of his DNA sampling, discovers that his Mum whose grandparents were originally from Cornwall, has a maternal lineage which in fact stretches back to East Eurasia and America. In Samoa, Oscar who is expecting the envelope to confirm his Polynesian roots is shocked to discover that his paternal lineage goes back to Central and South Eurasia. This discovery suggests Asian ancestry as his modern day descendants are found in the Middle East and the Himalayas. With stunning photography of their Pacific to Asia voyage captured on HD, Nathan and Oscar replicate the journey taken by their ancestors in reverse, starting with the Cook Islands, AND SAMOA then Vanuatu and ending eventually in Taiwan. There they are amazed by what they discover.
