French mountain guide Romain de Lambert spent much of his childhood in a tiny village in Castagniccia, a remote area of Corsica. He shows the Bergauf-Bergab TV team the diverse possibilities in the local mountains: from sport and multi-pitch climbing in the Bavella to hiking through the lonesome Castagniccia and exploring one of the crystal-clear mountain streams. In his native village of Petriacciu, he proves that he has not yet forgotten the Corsican songs his grandmother once taught him.
