Five years after the events of
the previous film, Curt Reynolds steals his father's security
key card, and he and his girlfriend, Julie Walker, 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 and crash. 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. After she is revived, the two escape on Curt's bike. Julie experiences intense hunger so Curt drives to a store. Inside, Curt runs afoul of a gang, leading to a struggle that results in the shopkeeper being shot by a member of the gang. As they run from the store Julie bites the shooter’s arm. Curt and Julie flee from authorities in a van with the wounded shopkeeper. However, after the shopkeeper is accidentally shot in the head by pursuing officers, Julie's hunger for brains overcomes her and she feasts on his corpse, eating some of his brains. As the shooter's health declines due to Julie's bite, the gang attempts to track down her and Curt. 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, wounding Riverman in the process. Julie seduces the gang leader, then kills him and uses her new decorations to kill another gang member. A third gang member is saved from Julie by Curt, but then is attacked and killed by the reanimated shooter. Julie and Curt flee, but Julie's body becomes accustomed to the pain, and she turns on Riverman off-screen, infecting and killing him. The rest of the gang re-animates before the military arrives 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. He rescues her and inadvertently frees several other zombies, which then kill two scientists. In the commotion the base is set on fire and Curt is bitten. Curt's father tries to get Curt to leave with the rest of the military personnel but he realizes that he would be abandoning Julie, and also knows he is infected. Curt brings Julie to the furnace; when she asks where they are, Curt says "where we belong", and they kiss one last time before dying by
immolation. ==Cast==
