He never told us more. There was a deadly calm in the valley that summer, a slow, climbing tension that seemed to focus on Shane.Seen through the eyes of a young boy, Bob Starrett, SHANE is the classic story of a lone stranger. At first sight, the boy realises there is something unusual about the approaching man, but as Bob gets to know Shane, he realises that there is an inner sadness in him. SHANE is the story of a gunfighter who tries to hang up his gun but is drawn to the side of the boy''s family and other homesteaders in their struggle to keep from being forced off their land.
