A young dude insists upon mashing a girl who is passing and minding her own affairs. She turns him down coldly, but he still continues to shower his attentions upon her. Finally she breaks away from him and rushes to her home. Her brother and some of his friends are playing cards. She tells them of her episode, and they immediately devise a plan whereby they can give the flirt a lesson. One of the boys dresses in the girl’s clothes, and the rest of the boys each take seltzer bottles, and go to do damage to the young man’s appearance. He is still waiting when they come out, and the masher thinks the boy dressed up is the girl. He immediately pounces upon her and endeavors to force his attentions upon her. The boys with seltzer bottles now rush upon the scene while the man in feminine attire belabors the would-be masher with a parasol. The masher gets all that is coming to him, and the boys return homeward, much elated over the severe lesson they have administered to the impudent young man.
