Catherine Destivelle has deservedly become the most famous female climber in the world. In this film we see the history of her climbing career, and her latest feat in unprecedented climbing ascents. Catherine Destivelle earned her fame with historic climbs, such as the free ascent of the Nameless Tower in Pakistan, and solo winter ascents of the classic North Faces of the Matterhorn and the Eiger, climbs that have never been repeated by any woman. She also made her mark in sport-climbing as she captured the World Championship title.

Bonington's secret mountain is a documentary about alpinism that takes place in Sepu Kangri. It was directed by Martin Belderson in 1999 and produced by Northern Films. It features Chris Bonington, Charles Clarke, Scott Muir, Elliot Robinson and Graham Little.
