A poor writer discovers that a species of rats has banded together to impersonate humans and supplant them unnoticed, in a manner reminiscent of the transformations in Eugene Ionesco's Rhinoceros, or the covert conspiracy of pod-people in The Invasion of the Body Snatchers. This film's story is based on a book by the Soviet writer Alexander Grin.
