LAS VEGAS NATIONAL FINALS NIGHT 4 (TV-PG)
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 – “Grip and Tip,” “Iron Summit” and “Pipe Dream.” 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.
