American Ninja Warrior

The season's top competitors attempt to conquer all four stages of the world's toughest obstacle course, beginning with Stage 1, which features eight grueling obstacles, including the new Roulette Row and Diving Boards.

On the second night of the four-week National Finals, top competitors, including Jessie Graff, Grant McCartney, Drew Drechsel and Mathis "The Kid" Owhadi, tackle Stage 1, featuring eight obstacles that must be completed in 2:30 to advance to Stage 2.

The competition heats up in Las Vegas as 28 competitors move forward in an attempt to conquer Stage 2 at the National Finals, where six dynamic obstacles await, including three new to the course - Giant Walk the Plank, Snap Back and Grim Sweeper.

For the first time in four years a winner will be crowned on the finale of "American Ninja Warrior." A select group of competitors move forward in the competition to face stage three which features seven daunting obstacles; three new to the course this year - "Battering Ram," "Curved Iron Maiden" and "Dynamic Pole Grasp." The elite few who conquer stage three move on to stage four, a final climb up Mt. Midoriyama, which they must complete in thirty seconds or less. Finalists vie for a $1 million prize and the title of "American Ninja Warrior." Matt Iseman and Akbar Gbajabiamila host and Zuri Hall reports from the sidelines.
