The Giant Spider

When radiation left behind by atomic weapons testing creates a gigantic killer mutant arachnid, it's up to a trio of scientists (Mike Cook, Billie Jo Konze and James Norgard), an Army general (Mark Haider), and a newspaper reporter (Daniel R. Sjerven) and his fiancée (Shannon McDonough) to figure out how to stop the hungry beast from devouring the entire county.
