She's To Die For.
In Return of the Living Dead Part II, the chemical Trioxin turned people into flesh eating zombies. Now the government is trying to control these unstoppable cannibalistic killers.
The splatter-fest starts when a young man uses the chemical to bring his girlfriend back to life. It's a state of the art special effects show as she starts a chain reaction of the living dead by eating the only thing that will nourish her... human brains.
