Ultimate Ninja Challenge

Nine modern-day warriors rely on the lessons of the ninja after being dropped into three brutal environments, including a frozen glacier, a frigid swamp and a wind-battered mountainside.

Pushed to their limits on a barren, battered island, the nine survivalists are desperate for food, water and fire; the brutal conditions causes one warrior to reach a breaking point.

Rafting through frigid, mountain rapids tests the survivalists' will and ability to work together.

To cross a 90-foot vertical gorge, the survivalists must work together to build a rope bridge; one warrior must overcome a debilitating fear to complete the challenge.

Racing against time, the survivalists must carry a 125-pound captive through brutal terrain, including sheer drops, mountain gorges and frigid waterfalls; one warrior is given an ultimatum by his teammates.

Captured, bound and blindfolded, the warriors must escape the Canadian wilderness before sunrise.
