The Office of Scientific Investigation (OSI) sends their A-Men (A for atom) agents to investigate reports of unusual magnetic activity in various communities. Their investigation leads to a scientist who's been experimenting with an artificial radioactive isotope. His microscopic creation takes on a life of its own, growing rapidly as it absorbs energy from its surroundings while emitting radiation and intense magnetic energy. Hilarity does not ensue.
