Dropped into three brutal environments - a frozen glacier, frigid swamp, and wind-battered mountainside - nine modern-day warriors try to survive using the lessons of the Ninja.

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

Rafting through frigid, mountain rapids tests the survivalists' will and ability to work together. A brutal injury could take one of the warriors out of the challenge.

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

Captured, bound, and blindfolded in the dark, the warriors must escape the Canadian wilderness before sunrise. One survivalist goes rogue.
