Plot

Having recently witnessed the horrific results of a top secret project to bring the dead back to life, a distraught youth performs the operation on his girlfriend after she's killed in a motorcycle accident.

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

Colonel Reynolds and his group of government scientists continue their work on re-animating the dead for military use. His son Curt and his girlfriend Julie use Dad's security pass to sneak in and watch the proceedings. Later when father and son have a disagreement, Curt and Julie take off on a motorcycle and Julie is killed in an accident. Grief-stricken, Curt takes her body to the lab and brings her back to life. Curt must help Julie deal with her new existence as military agents and local gang members try to find them.—Ed Sutton <esutton@mindspring.com>

Curt loved Julie very much. So much so, when she asked Curt to break into his Father's top secret army test center he agrees. What they discover is that they are testing the zombie gas to see if it can become a usable bio-weapon against terrorist and communist countries. They escape after letting one of the monsters loose and while in the mist of a blind panic, Curt crashes his motorcycle. Killing Julie when she goes flying off the bike. Curt can't live without her and again sneaks on the base, (great security) and uses the gas on Julie. Now Julie starts to act strange and when she takes a bite out of a Latino gang member, they are chased and perhaps a new wave of zombies maybe unleashed on the unsuspecting city.—Zedd

Teenager Curt Reynolds steals his father's security key card, and he and his girlfriend, Julie, explore the military base where his father works. They observe Curt's father, Colonel John Reynolds, Col. Peck and Lt. Col. Sinclair overseeing an experiment with a deceased body. The corpse is exposed to 2-4-5 Trioxin gas, which re-animates the corpse into a zombie. The military hopes to use zombies in combat. However, they are impossible to control as their hunger for human brains causes them to constantly attack. To deter the zombies' vicious nature, Sinclair suggests permanently attaching the zombies to exoskeletons that will immobilize them when they are not in battle. Reynolds prefers a method referred to as "paretic infusion", which involves firing a chemical projectile into the forehead of the zombie. This causes an endothermic reaction, freezing the zombie's brain and temporarily immobilizing it. When the paretic infusion method is tested on the zombie in the lab, it is only successful for a few moments, wearing off much faster than expected; the zombie breaks free and attacks a scientist, biting his fingers off before bashing his head against a wall, killing him. Infected by the zombie's bite, the scientist re-animates and attacks another technician. The initial zombie and the reanimated scientist are paralyzed with bullets and the survivors in the room are quarantined. Reynolds is removed from the project and reassigned to Oklahoma City, while Sinclair is promoted to head of the project. Reynolds informs Curt that they will be moving, something they have done multiple times, but Curt refuses. He rides off on his motorcycle with Julie. While they are speeding down the road, Julie playfully grabs Curt's crotch, causing him to lose control of the motorcycle. Julie is thrown from the bike into a telephone pole; the impact kills her. Curt brings Julie's corpse to the military base. Using his father's key card, he accesses the Trioxin gas to reanimate her. This leads to Julie and Curt dealing with the effects of Julie being dead - not feeling pain and having no desire to eat normal food - and what they are to do about her condition. Julie becomes hungry and Curt drives them to a store. A gang talk about her as she is eating snacks on the floor. Curt becomes angry and accidentally hits one of them. During the ensuing brawl the gang leader Santos shoots the shopkeeper. Julie one of the gang members Mogo. The alarm goes off and the gang flees. While Curt and Julie are in a van with the wounded shopkeeper who gets killed by getting shot by a one of the cops, Julie is overcome by her hunger for brains and eats his brains before Curt stops her. The gang chases Julie and Curt through the city, not realizing what is happening to their infected friend. Julie and Curt hide from the gang in the sewers, where they encounter Riverman, a vagrant who shelters them. Julie discovers that extreme pain seems to temporarily make the cravings to feed on humans go away. She mutilates her flesh with various items of junk found around Riverman's lair, until she is adorned with spikes, nails, and shards of glass sticking out of her flesh. The gang tracks Julie and Curt down. Julie seduces the gang leader, then kills him and uses her new decorations to kill the rest of the gang. Julie's body becomes accustomed to the pain, and she turns on Riverman, infecting and killing him. The gang re-animates before the military arrive and neutralizes all of the zombies. When the zombies are captured, Curt realizes Julie is going to be used as a weapon and goes into a rage, freeing the zombies which then kill the soldiers (including Sinclair). In the commotion the base is set on fire and Curt is bitten on the arm by the same zombie from earlier in the fim. Curt's father tries to get Curt to leave but he realizes that he would be abandoning Julie, and realizing that it's too late for him. Curt brings Julie to the furnace; when she asks where they are, Curt says "where we belong", and the two lovers kiss one last time as the flames surround them and the screen fades to black.
