A youngster looking for something to break the monotony of the everyday life which a boy leads, chances to spy a Chinese snuff advertisement. Of course, the youngster sees a joke ahead, and invests his last five cents with the hope of making everyone miserable, which he accomplishes when he buys the snuff and begins scattering it around. His first victims are two women standing on the corner, and when the snuff is thrown their way they quickly change from an animated conversation to a sneezing match. He next boards a passing street car, and you can imagine what happens when he throws the snuff about the car; of course it takes effect at once, and all the handkerchiefs are brought into play with the hope of stopping an awful sneeze. The boy continues on his sneezing route by entering a revival meeting and breaking that up. He then goes home, and lo! his sister, who happens to have company, is his next victim. Just as the youngster enters she is demonstrating her vocal powers to her friends. When the snuff is thrown around the room it changes her singing into sneezing, and every one sneezes. The boy continues this until everyone has felt the effects of the snuff. Finally the youngster gets it himself, and the picture ends with him sneezing worse than any of his victims.
