Description
On July 3, at the Uneeda medical supply warehouse, foreman Frank tries to impress new employee Freddy by showing him military drums that wound up in the basement of the building. Frank accidentally unleashes the toxic gas in one of the barrels, which seemingly melts the cadaver inside and reanimates another cadaver stored in a meat locker. Joined by their boss Burt, the three discover that every part of the zombie can survive independently. Burt has the zombie incinerated at a nearby mortuary by his friend Ernie, but this inadvertently causes the deadly gas to contaminate the air, creating a toxic rainfall that reanimates the corpses in a cemetery.
Meanwhile, Freddy's girlfriend Tina and his friends Spider, Trash, Chuck, Casey, Scuz, and Suicide arrive at the cemetery to meet Freddy at his job. Tina enters the warehouse first and wanders into the basement, where she encounters the reanimated but horribly disfigured cadaver from the barrel that was assumed to have dissolved. The rest of the group arrives shortly after and saves her in the nick of time, although Suicide is killed. After Casey realizes she saw Freddy entering the mortuary, the group attempts to reach him through the cemetery, where they are attacked by the re-emerging zombies. Trash is killed and Chuck and Casey flee back to the warehouse, but Spider, Tina, and Scuz reach the mortuary. The three discover Frank and Freddy growing ill from their exposure to the gas, with a medical test implying they are no longer alive. When Burt and Ernie learn of the dead rising from their graves, they barricade the mortuary thereafter. Scuz is killed while protecting the barricade and the zombies eat the paramedics and police who arrive on the scene.
With Frank and Freddy showing signs of becoming zombies themselves, Burt has them locked in the chapel, accompanied by Tina when she refuses to abandon Freddy. Freddy soon attempts to eat Tina, prompting Burt, Ernie, and Spider to rescue her by reopening the chapel. Frank manages to escape during the chaos and, still having control over his mind, commits suicide by immolating himself. Burt and Spider flee the mortuary in a police car, but the large number of zombies forces Burt to leave Ernie and Tina behind. Ernie and Tina hide in the mortuary's attic, while a blinded Freddy attempts to break in.
Burt and Spider manage to get back inside the warehouse where they find Casey and Chuck. After incapacitating the basement zombie, whom Spider names "Tarman", Burt attempts to contact the police but learns they are being massacred by the zombies. Burt then decides to call the number on the military drums, which reaches military officer Colonel Glover. Notified that the zombies have taken over the area, Glover has the town destroyed by nuclear artillery on the morning of July 4.
In the wake of the nuclear strike on Louisville, Colonel Glover is heard telling his commanding officer that everything went as planned and that the results couldn’t be more positive. Only a small area was destroyed, he says, and casualties are limited; plus, the rain is putting out the fires. As he speaks, more zombies in Resurrection Cemetery are heard screaming in their graves, indicating that the invasion is about to begin again.
