In 1951, aluminum company Alcan striked an agreement with the British Columbia government to begin construction on a hydroelectric project that would forever alter the landscape of the Nechako river and displace the entire Cheslatta community from their traditional village site. At the time, Alcan provided $5000 to the University of British Columbia to conduct an emergency expedition in the soon-to-be flood zone, but efforts were cut short and history was lost to the rising reservoir waters.
​
Fast forward to today, and Alcan (now Rio Tinto) is making efforts to rewrite the wrongs of their past, working with the Cheslatta Carrier Nation to better understand where things went wrong and how they can do better going forward. In the documentary we meet a crew of archaeologists working with Cheslatta to salvage, preserve and study cultural artifacts - some spanning 10,000 years old - that have been lost due to the flooding.
