Fatty admires the young pianist and singer in the apartment across the way, and the notes he casts through her window enrage her husband, who does not appreciate his wife's talent. He threatens Fatty. That same night a burglar gets into the pianist's apartment while her husband is out. Summoned to the rescue, Fatty crosses one window to another on a clothesline, with the worthy intention of chastising the thief. He has the misfortune, however, to land in the lady's room, where he is found by her returning husband. Quite a commotion follows, until the husband's bullets give out. The burglar, meanwhile, has escaped to the cellar, whence he makes his getaway.
