Dave, the swiftest waiter in Ho-Bohemia, is of a suspicious nature anyway and the whiskers of the two mysterious persons talking in a whisper nearby had already put him wise to the fact that they were anarchists. There was a pretty girl at the next table, and he could not get it out of his head that their plotting somehow meant danger to her. He was so distraught that he neglected his customers, and was finally fired from the beanery. He followed the two mysterious men. They arrive at an athletic field, where sports are taking place. The two men conceal themselves in the bushes, and begin to fire the magic Jazz-bo pellets that they had invented at the athletes, by means of a small gun. The "dope" has the desired effect, and the athletes are slowed to a walk, and sail through the air over the hurdles. Dave hears them plan a meeting for that night.Dave is on hand. He fixes a board from a tree outside the window to the windowsill. He sees them hang a bottle containing the pellets to the chandelier. Skating down the board on his roller skates, he crashes into the room and snatches the bottle as he flies. Then he discovers that the house is the home of the pretty girl. He tells her that he has saved her from the deadly Jazz-Bo. But she calls him a thief and joins the chase after him. He loses one skate and they are gaining. Then it occurs to him to throw some Jazz-Bo at his pursuers. He does so and they are slowed down at once. Dave reaches the bank of the river just as the anarchists shoot the bottle of Jazz-Bo in his hand. It explodes in a cloud of smoke, and Dave is thrown into the water. He sinks and then rises so slowly that he is drowned on the way up.Moving Picture World, October 20, 1917
