Return of the Living Dead 3

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.
