[1] As described in a film magazine,[2] Kentuckian Major Lee Pomeroy (MacGregor) has been obliged by financial circumstances to sell his race horse Chain Lightning, which is really the property of his daughter Peggy (Little).

She comes home from school in Washington to learn that the horse has passed to the possession of Colonel George Bradley (Girard), her father's enemy.

The horse is entered in an important race and Pomeroy wagers all his remaining funds on his former track star.

Red Rollins (Carroll), the jockey to ride the horse, makes advances on Peggy but is repulsed.

Chain Lightning survives in the Library of Congress collection Packard Campus for Audio-Visual Conservation.
