From America, England, France, Italy and Japan. Five climbers from each corner of the earth; 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. All pitches are freed, including the now famous 5th pitch, 8c , freed by Yuji on the last day of the trip, and through all the adventure, Caroline re-discovers the magic of a place long forgotten. The name Zembrocal refers to a famous Creole dish made from mixed varied ingredients that still maintain their original identities.
