Britain's leading rock climbers demonstrate their skills. In the Lake District, the 71-year-old Rusty Westmorland and Monica Jackson climb Napes Needle. In Idwal, Gwen Moffat, the first woman mountain guide in Britain, leads a climb on the Idwal Slabs, seconded by her husband Johnnie Lees. At Windgather Rocks, Geoff Sutton and Gordon Mansell teach a group of novices some basic climbing techniques. The documentary also includes reflections on mountaineering and climbing by George Abraham, Geoffrey Winthrop Young, George Band and Joe Brown. The film ends with shots of Brown leading Suicide Wall at Idwal.
