La peur des microbes

A studious-looking old fogey becomes alarmed by a newspaper announcement to the effect that a deadly microbe which spread influenza is loose in the air, and that there are already several hundred victims. He becomes terror-stricken, and runs straight to a chemist's where upon his inquiry they sell him a liquid which must be administered through an atomizer. This he takes, and sets forth on a crusade against influenza. (imdb)
