The stalwart adventurer, Heeza Liar marching on to Mexico City to quell the revolution single-handed, grows footsore and weary and, in consequence, meeting with a wandering burro, mounts his back. The jack objects to this imposition and proceeds to unseat the Colonel. He has taken on a more difficult task that he at first supposed for Heeza Liar is prouder of his horsemanship than of any of other accomplishments. But Jack finally dumps the Colonel on the street and with his heels sends him through a window and into a bed already occupied. The occupant, a rebel, is peeved at the intrusion and in the battle which follows Heeza emerges triumphant. Not only that, but he steals an aeroplane and with its anchor hooks Huerta and after depositing him on Mars delivers the Mexican's sword to President Wilson and receives the medal of the Legion of Watchful Waiting.
