Tunnel to Hell

After a massive overnight blizzard, conductor Jim and engineer Jordy are hauling $50 million worth of freight from Vancouver—straight into the heart of the avalanche zone. High in the mountains, avalanche technician Derek makes a startling discovery and prepares to detonate a man-made snow slide. The snow-removal crew tackles giant ice columns that could spell disaster for passing trains. And, after the avalanche bombing, it's all hands on deck. Meanwhile in Ontario, off-gridder George fills an entire car with firewood for delivery to an isolated Northern community.
