The scene is that of a large experimental laboratory equipped with various scientific appurtenances, drawings, models, etc. A huge airship is carefully guided out of the building and all preparations for a trial trip, with a great deal of pomp and under imposing formalities, completed. En route the learned inventor and his assistant drop anchor to appropriate a basket of victuals carelessly set to one side by a gossiping maiden. Later on an accident causes a hurried descent in a parachute, but the landing is made on an island inhabited by cannibals. Both men are condemned to the stew pot, but the queen does the Pocahontas act, and the captain is saved from death, whereupon he rushes to the aid of his assistant, whom he rescues in the nick of time. The return trip is promptly undertaken and the final lap made in an auto. The men are received with great honors and glory by their fellow citizens.
