The expedition travels to Antarctica, one of the purest places on the planet. Their goal is to complete the last degree sky, a 111-km walk on skies that will take them across to the southernmost point, the south pole. They arrive from Chile to the Union Glacier, a support base and start preparing to cross Antarctica.

At Union Glacier, the adventurers will have several days to acclimate and train before leaving for the 89th parallel. During this stay they meet Robert Swann, the Antarctic defender, from whom they learn about the Antarctic Treaty signed by several countries set to expire in 2041.

Once they arrive at the 89th parallel, the explorers are left to themselves, planes and support teams drop and go and so a 10-day walk to the South Pole begins. As challenges arise Juan reminisces on conversations, he had with first adventurers to fly in special costumes over Antarctica. Our explorers continue on their journey and learn of a brand of off-road vehicles especially prepared to tour the continent without leaving more than their track marks.

The days are getting colder and harder. For our 3 friends their dream of reaching the south pole seems to be getting father away. But they are committed to working with the hostile environment and learning to appreciate the beauty and vastness of nature, respecting it every step of the way. The quick encounter with a group of women from the British Army encourages them to push through.

The explorers finally completed their journey to the South Pole. They invite us into their celebration where we learn how impactful it has been and how their perspectives have changed. A heightened appreciation for life is present and a newfound understanding of why the Antarctic Treaty must be preserved shared. The explorers adopted Robert Swann's mission: "protect Antarctica and educate the world on the importance of the 2041 treaty, so that this place remains as pure and pristine as they found it."
