Fan favorites from season one stop by to lead the crew in the final team challenge hanging sheet rock, and in the individual challenge laying shingles.

The final four crew members, Scott, Sarah, Zeus and Swifty, put it all on the line and compete in a series of challenges to be crowned the champion and win the $200,000 prize.

Phil Keoghan welcomes the 12 new crew members to Camp Pendleton Marine Corps Base in Southern California, where season one winner Marine Veteran Kelly "Murph" Murphy returns to kick off the new season and guide the crew through their first challenge: race to receive cargo dropped from a C-130 plane.
