Teams are challenged mentally and physically when tasked with pushing 24 heavy barrels uphill and arranging them in a specific order at an oil field, and one crew member must conquer a fear of heights to climb a telephone pole.

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.
