Killer Rats on AllMovie

The rats have taken over the lab in this tale of rodent terror that's sure to give even the most stringent animal lover nightmares. The Brookside Institute has long been known as the place the wealthy go to dry out and get it together, but deep within the walls of the pricey rehab center lurks a dark secret. Years ago, the scientists who worked in the institution conducted a series of gruesome experiments on countless lab rats, and though the scientists are long gone, the genetically mutated rats have multiplied, turning the pricey institute into their own personal breeding ground. With the patients in lockdown and the rats gaining an insatiable appetite for human flesh, it appears as if rehabilitation is about to take a back seat to survival for the patients of Brookside.
