The Daring Young Man is hotshot-reporter Don McLane, played by James Dunn. Always on the prowl for a good story, McLane is persistently outscooped by his rival, sob sister Martha Allen (Mae Clarke). After several reels of double-crossing one another, hero and heroine give in to the inevitable and fall in love. But as Martha waits at the altar in her wedding gown, McLane is off on another crusade, this time getting himself arrested to expose corruption within the prison system.
