McLintock!

McLINTOCK! He Tamed the West--But Could He Tame Her? Cattle baron, banker, and model citizen George McLintock (John Wayne) has the world in his hands. The only thing missing is his wife, Katherine (Maureen O'Hara), who left him two years earlier, suspecting him of adultery. In an effort to get on with his life, McLintock saves a beautiful but impoverished widow from resettlement and hires her as his cook, welcoming both her and her two children into his home. Sparks begin to fly and McLintock's simple and serene lifestyle comes to a crashing halt as an unexpected turn of events results in brawls, gunfire, an Indian attack, the engagement of his only daughter and...the return of Mrs. McLintock!
