An English doctor saves a Mexican revolutionary leader (Tepepa) from the firing squad in order to exact personal revenge for the death of his fianc�e. But things are not so simple, as the revolutionary is a popular man with the masses and his version of events throws doubt as to his guilt in the matter. The doctor is not swayed but, as political hostilities are renewed, both men are engulfed in the increasing violence and find themselves pursued by the ruthless Colonel Carrosco who is determined to recapture Tepepa and make an example of him to the peons who see him as a hero.
