"Quo Vadis? Biggest production ever staged. Straight from Broadway. Lavish Scenery. Renowned Stars. A Trainload of Scenery. For Two Nights Only, Saturday and Monday. Parquette 20 cents, balcony 15 cents." Thus reads the advance posters of a barn-storming theatrical troupe, and before the glue is dry half of the inhabitants of the village are gathered at the station to await the big show. After the show arrives in town one of the busiest men is the property man. He is sent to get supera to impersonate gladiators, Roman soldiers and the rabble. There are fights between them for the best helmets and other accouterments of war. And then there is the bull, a cow that gets into the leading lady's dressing room with the result that she is forced to move to another. When the manager fails to come through with the salaries after the show there is a strike, led by the leading man. After securing a new company, made up mostly of townsfolk, the show is about to begin, when it is discovered that there is no Ursus, and no bull. A bull is manufactured and the property man is forced to become the hero.
