A scientist, Professor Calvin Q. Calculus, successfully creates a portable hole invention, despite disapproval from his nagging wife. He displays his creation in a newsreel, showcasing the various uses for a portable hole: Rescuing a baby from a safe, cheating at your golf game, giving dogs a new place to bury their bones and escaping from housework. Spurred by the film, a thief (later named by the press Holey Terror), steals Calvin's portable hole and uses it for criminal purposes, including emptying Fort Knox and abducting a dancing girl from a burlesque house. However, he is chased by the police, who fall through another of his holes. He even tried to escape by using a very large portable hole; but ended up becoming a train tunnel exit as he would later be chased by a train. The police continue to chase Terror, until he is backed against a wall; he uses the last portable hole in the briefcase to go through the wall and seemingly escape, but it's revealed that the other side is inside a prison. Holey Terror at last is caught. Calvin reads about the arrest in the paper and is glad and tells his audience that crime does not pay, but Calvin's domineering wife chews him out for not treating her right. In retaliation, Calvin creates one more portable hole and throws it on the floor. The wife steps in it and falls through it. After a few seconds, Satan comes up the portable hole, throws her back to Earth and replies: "Isn't it bad enough down there without her?"
