30 civilians begin the most intense physical and mental challenge of their life as they begin The Selection, led by six Special Operations veterans.

After only two hours of sleep, the instructors lead a grueling day of Navy SEAL training in the Pacific Ocean that pushes the participants to the edge.

The Instructors send the remaining 15 participants to rescue a "downed pilot," an exercise designed to test the teamwork of the group as well as the leadership of a few.

The participants go out on the ultimate game of hide and seek, where they are tasked with camouflaging themselves in a hide-site to evade detection by the instructors.

The group is led to a swimming pool where the Navy SEALs put the remaining candidates through the most dangerous exercise yet--drown proofing.

The remaining candidates are forced onto an eight-mile timed ruck march while carrying 50 lbs. on their backs. One candidate reaches his mental breaking point.

Instructor Care leads the remaining participants through an exercise he calls "integrity stations." One candidate fails to complete the course.

The candidates must complete a field training exercise. They will face the most difficult challenge of their life, and only those who finish will pass The Selection.
