The Ultimate Vampire Resource and Directory

Rancher Cole Hillman is having problems with the rabbit population on his ranch, who are destroying his crops. College president Elgin Clark, as a favor to benefactor Cole, calls in zoologists Roy and Gerry Bennett, who create an (untested) serum for disrupting the breeding cycle of rabbits. However, their daughter Amanda has become attached to the rabbit that has become the serum's test subject and switches it with a rabbit from the control group; she is thus able to take the injected rabbit out of the controlled environment of the lab. The injected rabbit gets away and breeds. The serum doesn't disrupt their breeding cycle, but does something worse: it causes the rabbits to become gigantic meat-eaters. When several people are slaughtered by the carnivorous carrot-munchers, Roy and Gerry attempt to find a solution before the whole of the American Southwest is overrun by giant rabbits.
