Bruce travels to the far north of Canada to live with the Caribou people and witness their annual spring hunt. The Gwitchin tribe has hunted migrating caribou in the Arctic wilderness for thousands of years, but this tradition is now under threat from oil exploration. Bruce then heads south to the tar sands of Alberta, home to the second largest oil reserves in the world, to discover how native people cope when the oil industry moves into their territory.
