A guileless young man, over-modest, determines to start a crusade against all sights that offend his shrinking nature. An innocent post card, sent by an admiring friend, picturing a pretty chorus girl, grates on his delicate nerves, and he has a fit. An unexpected corset demonstration in a store window causes him to beat a blushing retreat. The sight of a poster displaying the charms of a prominent burlesque actress, doing some high and lofty kicking, puts him in a frenzy. Around an undraped statue of a fountain in the park he places his overcoat, to the amazement of an unsentimental Irish policeman, who promptly marches him to the lockup. On beholding a lady, in a low-neck dress, at the opera, he faints and causes a sensation. He is shocked when he visits a man of family and beholds baby in its bath: nor does he wait upon the older of his going, but abruptly leaves. So on through a series of adventures, all of which he relates to his friends, who finally determine to cure him of his peevishness. They arrange a fitting climax that causes him to forever forswear his prudish scruples and act like a man of sense.
