Mantracker

Two people take off into the bush with a map, a compass and a head start. The
tracker is on horseback, armed with a local guide and an arsenal of forensic
skills. The prey have 36 hours to reach a finish line some 40 kilometers away
without getting caught. How they escape is up to them.

The "Mantracker" is Terry
Grant, a 12-year-veteran of the Alberta Foothills Search and Rescue
Team,
and an expert in using clues such as footprints, probable path, and
other signs
of human presence to track prey.
