Lee Remick stars as Jennie Jerome, better known as Lady Randolph Churchill through her marriage to the son of the 7th Duke of Marlborough, and mother of the most celebrated British politician of all time, Winston Churchill. Famed for her beauty and intelligence, the vivacious, American-born Jennie was a driving force in the lives of both of these great men; it was at her dining table and in her salon that the young Winston met and conversed with the most brilliant political figures of the age. Jennie recognised her son's genius for politics and was able to nurture and foster it, and Sir Winston would repeatedly pay homage to her energy, courage and dedication.
