Three friends arrange to meet in the forests of the Jura mountains to go to Chalet Carroz, managed by the Geneva section of the Swiss Alpine Club. After having received a warm welcome from the three young managers, they will have the opportunity to learn more about the activities of the SAC and will be involved in an expedition to the Zanskar mountains in the Himalayas. It will be a sort of baptism, allowing them to understand a more profound way of experiencing the mountains.
