Competitors take on a series of "Five alarm" challenges at a firefighter training facility, where they must clear a 60-foot-long section of brush, save a victim from a simulated disaster zone and extinguish a fire before rappelling down from the top of a four-story building.

The final five competitors battle to be crowned the champion of TOUGH AS NAILS and win the $200,000 prize! Plus, the finalists get a much-needed boost when their loved ones cheer them on.
