A Chicago society matron, wife of a prominent business man, sends her youngest son abroad to be educated. He returns to mama accompanied by his college chum, Lord Swagger. Both are exquisite of the latest English type. They arrive in Chicago with English valets, call upon the Father, who, when he sees them, throws a fit. A sister of Lord Swagger arrives and is given a social welcome. Algy, the American, falls in love with her. Lord Swagger falls likewise for Algy’s sister. They propose in characteristic fashion and are accepted. A few days later, while out for a stroll, don’t ye know, vaudeville performers see the exquisites and decide to imitate them in a vaudeville sketch. The manager of the theater agrees and advertises Algy and Swagger as the latest hit. They see themselves advertised and decide to take in the show, which they do, proving that they have been taught other things than manners. The vaudevillians lionize them and invade their apartments. Mother, father and two engaged young women make a sudden call. The vaudeville performers dive under the table and make their escape. The family is shocked; the young ladies hand back the engagement rings; the father orders the exquisites out of the house; the brother follows and puts them away in his business apartment; then bids them good-night, while there they make a capture of burglars. This reinstates them in the good will of the father, who makes a proposition to take them into the firm if they will become Americanized. They decide to try, and we finally see them as up-to-date American business men.
