Aging rancher George McLintock (John Wayne), a wealthy self-made man, is forced to deal with numerous personal and professional problems. Seemingly everyone wants a piece of his enormous farmstead, including high-ranking government men, McLintock's own sons, and nearby Native Americans. As McLintock tries to juggle his various adversaries, his wife Katherine (Maureen O'Hara), who left him two years previously, suddenly returns. But she isn't interested in her husband -- she wants custody of their daughter Becky (Stefanie Powers).
