The teenager Curt Reynolds steals the security key card from his father, Colonel John Reynolds, to snoop in the military base where his father works, with his girlfriend Julie Walker. They witness a top-secret experiment of reviving corpses for combat by Trioxin led by Colonel Reynolds, Colonel Peck and Colonel Sinclair. However, the greatest problem is to control the zombies from their hunger for human brains and their project fails with casualties of scientists. Curt and Julie flee from the base, Colonel Reynolds is removed from the project, being transferred to Oklahoma, and Colonel Sinclair assumes the command of the project. When Colonel Reynolds tells his son that he will be reassigned to Oklahoma City, Curt says no and decides to leave home with Julie. While riding his motorcycle, Julie plays with Curt and he loses control of his bike, throwing Julie to a pole and killing her. He uses his father's card to bring Julie inside the laboratory in the base and reanimates her using Trioxin and creating havoc in the base. They succeed to escape from the base, but when Julie's hunger increases, their problems begin.—Claudio Carvalho, Rio de Janeiro, Brazil
