The film was adapted by Paul Ryder from the 1957 Rene Ray novel of the same name; a TV serial adapted by Ray aired in Britain in 1956.
A monomaniacal scientist, Dr. Laird (played by Alec Mango), has invented ultra-sensitive magnetic fields, which attracts objects from space. Strange things begin happening, including a freak storm, and insects and spiders mutate into giant monsters. An alien spaceship appears over London and mankind is warned against the dangers of this scientific experiment.
