Two climbers, Dany Badier and Françoise Dassonville, swim to explore an underground cave in the Calanques, near Marseille, then equip themselves with climbing gear to scale the spectacular cliffs of the Calanques. Their ascent culminates at the summit of the Grande Candelle. Directed by Gilbert Dassonville in 1970 and produced by Cérès Films, this film won first prize at the Trento Mountain Film Festival in 1967.
