On September 11, 2001, the unimaginable transpired when devastating attacks on the World Trade Center forced the shutdown of the entire U.S. airspace. Thousands of kilometres away in Gander, Newfoundland, a group of Nav Canada air traffic controllers suddenly had the lives of 33,000 people in their hands and had to think fast to find a place for them to go. Discovery uncovers how these unsung heroes managed to safely land 224 planes in four hours, without incident.

Edna and Harley Whalen, an elderly couple, give shelter to Wade, a suspected murderer on the run. The Whalens do all that they can to protect Wade but evil begets evil in this world, and even more so in Sanctuary.
