A spate of unusually aggressive rat attacks calls Doomwatch into action. The victims include the elderly, children, other small animals, and other relatively defenseless targets, and to the alarm of Quist and his team, it would seem that along with this atypical vicious streak, there are signs that the rats are beginning to use rudimentary tools and reasoning. The rapidly mutating, evolving rat population is a dire threat to the human race, and John Ridge meets the scientist who originally released the rats into society…and finds that he is attracted to her. With the death toll mounting, those feelings may be a fatal distraction for more than just the two of them.
