"W for Walter," directed by Rossana Podestà and Paola Nessi, is the last gesture of love that Rossana, who passed away in December 2013, offered to Walter Bonatti, recounting with intense sweetness and simplicity the life of the great mountaineer and explorer. Walter Bonatti and Rossana Podestà met when both were at the end of their respective careers. She was a renowned international actress, he was a beloved explorer of distant lands, and, above all, the man who shaped the history of world mountaineering. Two extremely different lives that, as Rossana recounts in the film, slowly slid into each other, creating an unbreakable bond.
