Pro wrestler John Cena is joined by an elite group of military mentors who command contestants to either persevere or give up while their teams are pushed to the limit.

WWE superstar John Cena reveals the next challenge, and the losing teams must send one teammate to compete in The Circus.

The competitors are challenged to break down and set up camp as a test of their resourcefulness and ability to think on their feet.

The competitors are challenged to memorise and re-create specific sets of symbols to test their observation and communication skills during physical exertion; one team will be safe from facing the circus.

To test survival skills, each team must make a shelter, purify water and build a fire. Only one team will win and be safe from the circus.

Competitors lead their teams in a challenge to cross a 60-yard field without letting their feet touch the ground.
