Edna Dusenberry, the charming twenty-year old daughter of Senator Dusenberry, is in love with handsome young Walter Force. John Cartwright, a corrupt politician and candidate for mayor, makes a deal with the Senator whereby he is to receive the hand of Edna in marriage. Edna holds opinions of her own upon the subject and goes to her fiancé, Walter, for advice. Walter's law partners hit upon a scheme to beat the corrupt politician. They tell their idea to Edna and she tells her father that she will marry the next mayor, the announcement to be made on the day after election. Cartwright, believing that he has won goes into the campaign with renewed vigor. Now the young people put their scheme into operation. Walter is put up as the reform party candidate for mayor and, after an exciting battle at the polls, wins by a good plurality. The next morning he calls at the Senator's home and reminds him of Edna's promise to "marry the next mayor."
