McLintock! presents screen giant John Wayne at his two-fisted best, with the beautiful, fiery Maureen O'Hara as the proverbial thorn is his side. The Duke stars as George Washington McLintock, a proud, defiant cattle baron whose daughter Becky (Stefanie Powers) is due home from college. But G.W.'s happy reunion with his daughter is tempered by the arrival of his headstrong wife (O'Hara), who left him two years earlier. Verbal fireworks explode, slapstick pratfalls bloom...and the Wayne-O'Hara "reconciliation" culminates with the biggest mudhole brawl this side of the Mississippi!
