Terror swoops through the heart of a city in the dead of night!

The Office of Scientific Investigations tracks down the source of increased magnetism and radioactivity in Los Angeles, and discovers that a man-made isotope is consuming available energy from nearby mass every few hours, doubling its size in the process. Although microscopic, it will soon become big enough to destroy Earth; and how to stop it is yet to be determined. (The film's Deltatron special effects footage is taken from the 1934 German sci-fi film GOLD.)
