Ultimate Ninja Challenge

Split into three groups, the survivalists are dropped onto a frozen glacier, into a frigid swamp and a on a wind-battered mountainside and must build shelter to endure the night.

The survivalists are desperate for food, water and fire. Using the ancient ninja principles of survival, they must work together as teams, but the freezing conditions and violent storms on Hutt Island push them to their limits.

On the survivalists' most demanding mission, another overwhelmed comrade caves. The remaining warriors must build rafts to navigate down a freezing river.

To cross a 90-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.

Racing against the clock, the survivalists must carry a 125-pound wooden captive through brutal terrain including sheer drops, mountain gorges and frigid waterfalls. One warrior receives an ultimatum from his teammates.

Captured, bound and blindfolded in the dark of night, the warriors must rely on the ancient ninja principles to escape from their bonds and return to their base camp before dawn in order to accomplish the mission.

Isolated and alone, each exhausted survivalist must prove themselves in a grueling, overnight solo mission. Those who survive the final challenge travel to Japan to receive a final lesson from the Ninja Master himself.

Through never-before-seen footage and face-to-face confrontations, the survivalists provide fresh insights into the most harrowing missions and intense conflicts when they are brought back together for the first time.

In the brutal cold of the unforgiving Pacific Northwest wilderness, nine modern-day warriors take on a relentless, 24-day survival challenge based on the ancient laws of the ninja.
