A cavalcade of English life from New Year's Eve 1899 until 1933 seen through the eyes of well-to-do Londoners Jane and Robert Marryot. Amongst events touching their family are the Boer War, the death of Queen Victoria, the sinking of the Titanic and the Great War.

Between world wars, the Whittaker's estate is sinking; only the iron will of Mrs. Whittaker staves off bankruptcy while she awaits her son John's return from the continent. To her dismay, he brings a bride: an American widow who races cars. The bride, Larita, thinks she and John will visit and then go to London, where he'll work and she'll race. But John is to the manor born, and mother is nothing if not a master at plans and manipulation. Soon it's all-out war between mother and bride, with John's father, a burnt out veteran of the Great War, in the bride's corner ineffectually. Mother has a plan to join with the neighboring estate; only Larita is in her way. Can't we all get along?
