Lois Wilson (as Lulu) is the spinsterish member of the Deacon family: "The family beast of burden, whose timid soul has failed to break the bonds of family servitude." Her brother-in-law is patriarchal Theodore Roberts (as Dwight Deacon); running the house with an iron fist, he is both a dentist and a Justice of the Peace. As the latter, he accidentally marries Ms. Wilson to his visiting brother Clarence Burton (as Ninian Deacon) while they are out for dinner. Schoolteacher Milton Sills (as Neil Cornish) is also interested in Wilson.
