From America, England, France, Italy and Japan. From each corner of the earth, five climbers - Sam Elias, James Pearson, Caroline Ciavaldini, Jacopo Larcher and Yuji Hirayama - attempt to open a new multi-pitch route on the basalt island of Reunion. Lost in the South Indian Ocean, Reunion is the childhood home of Caroline and, after traveling the world for several years as a professional climber, returning was something she had to do. By working together as climbers and friends, the team is able to open, ground-up, one of the hardest multi-pitch rock climbs in the world.
