Allan Code, Yukon filmmaker, goes on a northern journey to Yukon and Alaska’s most remote wilderness areas. For a year, Code follows the FortyMile Caribou Herd in its migration in order to tell their story of survival and how traditional knowledge and science saved them from extinction. This herd was once one of the greatest mainland herds in North America, counted at half a million animals in 1920; and reduced to less than 5,000 in 1970. This documentary is thematically about what we perceive as “natural” and what a natural environment might actually be. It’s about the “Memory Trap”; how we get used to a depleted world and how loss of keystone species sets a new “normal” at just a fraction of what it once was and what it can be. Individuals, agencies and First Nations governments stepped in at the last minute and formed a management plan that worked. Slowly, the herd began to grow again in the 1990s, but up until very recently, they continued to occupy only a tiny portion of their territory.
