His First Flame (1927)

Fire chief Amos McCarthy, a confirmed misogynist, counsels his nephew Harry Howells to avoid matrimony at all costs. Still, the lovestruck Harry is determined to marry his sweetheart Ethel. All that changes, though, when it turns out Ethel is a faithless gold-digger. Disillusioned, Harry spends the night in his uncle's fire house to try and forget his troubles... until the clamor of a fire alarm presents the bumbling Harry with a chance to be a hero.
