On a moonlit night, in a remote research laboratory, a major medical breaththrough is about to have deadly results. A chemical compound that was created to "hunt and destroy" deadly cancer cells has leaked from the hazardous waste disposal system into the building''s basement. Now, the rodents involved in the laboratory experiment upstairs are not the only rats in the facility that will become the ALTERED SPECIES.
Professor Schultz, a leading bio-researcher, has just determined that the addition of a new enzyme now enables his "hunt and destroy" formulation to regenerate for the length of time necessary to neutralize deadly cancer tumors. When three varying degrees of the new mixture are administered to ththree different rats and the rest poured down the faulty "Waste Hazard" sink, shocking side-effects result in a night of terror that is reminiscent of such blockbustere hits as SCREAM and ALIEN.
WALTER, PROFESSOR SHULTZ''s ambitous assistant, and a group of his college friends -- ALICIA, FRANK, CHELSEA, GARY and BURKE who had hoped to celebrate the end of the school year at "Dr. Frankenstein''s" lab, find themselves, instead, in a desperate struggle against an enemy that is intent on its mission to "hunt and destroy" them!
The startling truth about the mechanism that triggers the rat''s deadly behavior becomes the key to a daring plan by WALTER and ALICIA who are all that remain alive in the final conflict. Even if they succeed, the greatest threat of all still awaits them....
