These hard-core extremists call themselves "mountain dogs". They have a few tricks up their sleeves And on their ski poles as they tackle Southern California's Big Bear Mountain and attempt to lose the trackers on their trail.

They're sisters, but definitely not two peas in a pod. Lauren is an aspiring opera singer, while Jessica is a fitness instructor. How these talents will help them escape Mantracker through the mountainous terrain is anyone's guess.

Brothers and business partners Rene and Dave lead Mantracker on a chase through treacherous land full of lakes and woods. It's virgin ground for Mantracker, who brings his considerable skills to the boreal forest.

Mantracker adjusts his tracking skills to suit the California high desert abutting the Mojave. He's up against Chelsea- a volatile mix of bush smarts and spiritual instincts and Trev, the entrepreneur, who hopes his back-country experience and level head will take them to the finish.

Back for another chase around Elliot Lake, Mantracker is batting 500 in Northern Ontario, but it always makes him cranky! Andrew and Hainsley are fast-talking, city-slickers with a love of sports, the outdoors and themselves. Will they be putting Mantracker in the Hall of Fame? Or Taking him down for the count?

Siblings Brian and Julie have spent a lot of time together and feel their unspiken communication will help them "feel" their way to victory. They've go the bush experience- in Ontario. But now they're being chased by the tracker in British Columbia, and it's a whole new back country.

Mantracker goes in search of a pair of Newfoundlanders over the rolling foothills of the Long Range Mountains on The Rock's west coast. They all tackel the 'tuckamore' while the prey leave newfie 'treats' for Mantracker to get screeched.

Brothers-in-law Adam and Mike have book smarts, all right. They're both teachers. But will all that theoretical knowledge translate into solid strategy as they tough it out in the bush surrounding North Bay, Ontario?
