The common thread that connects all the protagonists of this story is the passion for Highline, a sports discipline that consists in walking on a suspended length of flat webbing. This discipline is a matter not only of physical and mental performance, it is most of all a matter of sociality. “Highliners” share an authentic relation of deep, mutual trust: almost every aspect of the journey is shared, and every single person has a great responsability for every other member. Every highliner has to play a crucial role in order to reach the final, common goal of the adventure: to walk in the sky.
