Honor. Courage. Commitment. For over 200 years, these are the words that have come to define the men and women who make up America's most elite fighting force - The United States Marine Corps. The technology and training techniques may have evolved over the two centuries since the USMC was founded, though the fighting spirit remains the same. By following new recruits from their arrival on Parris Island through their punishing trip through the Crucible - an unforgiving, fifty-four hour test of mental and physical endurance - viewers are finally able to witness the life-changing transformation from average civilian, to honored United States Marine. For the first time ever, top drill instructors, company commanders, and recruits offer an all-access glimpse at the inner-workings of the United States Marine Corps' top training facility.
