Allan Code's MEMORY TRAP: THE HERD THAT WOULDN'T DISAPPEAR weaves together interviews of biologists, elders, authors, conservation officers and hunters with footage from some of the most remote corners of the Yukon wilderness to tell the incredible story of the Fortymile Caribou herd. In 1920, the Fortymile Caribou herd had numbers in the 600,000's, only to dwindle to 4,000 in the 1970's. Follow Code over the course of a year through the remote wilderness of North Yukon and Alaska as he traces the story of the herd's survival and how traditional knowledge and science saved the herd from near extinction.
