Say you're in Banff National Park and you decide to go hiking in the mountains. Suddenly you find yourself at the edge of a cliff. You're lost, the wind is picking up and it's getting dark. Your survival may depend on the expertise of one of the park's Search and Rescue Wardens.

There are nearly 1,000 Wardens in Canada's National Parks, but only a small group has the real heart-pounding jobs. They're the specialists who get the call when a hungry cougar is on the prowl, a herd of bison needs to be wrangled or a raging forest fire is threatening a town. These are the men and women who are called when an ULTIMATE RESPONSE is needed.
