Alien brain parasites, entering humans through the mouth, turn their host into a killing zombie. Some teenagers start to fight against them.

In 1959, an alien experiment crashes to earth and infects a fraternity member. They freeze the body, but in the modern day, two geeks pledging a fraternity accidentally thaw the corpse, which proceeds to infect the campus with parasites that transform their hosts into killer zombies.—<crow_steve@hotmail.com>

In 1959, an alien throws an experiment from his spaceship to the space and the capsule crashes on Earth. The college students Pam and Johnny are dating in a parking area nearby the location and believe it is a falling star. Steve decides to investigate, but they are warned by Pam's former boyfriend, the police officer Ray Cameron, that a maniac is killing people in that area with an ax. However Steve leaves Pam and walks in the woods looking for the star and a slug-like creature jumps into his mouth. In 1986, the college students Chris and the disabled J.C. are best friends and Chris has a crush on Cynthia Cronenberg, who is the girlfriend of the cocky Brad. They decide to join Brad's fraternity to impress Cynthia and Brad tells that they need to bring a corpse and leave in front of another fraternity. They go to the Med School Laboratory of the Corman University and find Johnny's body in a cryogenic chamber. They remove the corpse from the chamber but get scared and leave the body on the floor. However, Johnny leaves the laboratory and releases slugs that transform people into zombies. Detective Ray Cameron is in charge of the investigation and initially believes that it is a prank. But soon he realizes that the campus is crowded of zombies.—Claudio Carvalho, Rio de Janeiro, Brazil

An alien experiment has gone terribly wrong turning people into zombies.Back in 1959 an ax killer is on the loose.Almost 30 years later 2 boys find his dead body in a cryochamber.He's a zombie with an alien slug in his brains causing the zombie epidemics.

In 1959, on board a space ship, two aliens race to keep an experiment from being released by a third member of the crew. The seemingly possessed third alien shoots the canister into space where it crashes to Earth. Nearby, a college man takes his date to a parking spot when they see a falling star and investigate. Unfortunately, it lands in the path of an escaped criminally insane mental patient. As his date is attacked by the axe-wielding maniac, the boy finds the canister, from which a small leech-like thing jumps out and into his mouth.

28 years later, Chris Romero is pining over a love lost, being supported by his handicapped friend J.C. During pledge week at Corman University, Chris spots a girl, Cynthia Cronenberg, and seems to fall instantly in love. To get her attention, he decides that he must join a fraternity. As a part of their pledge (although the frat leader who is dating Cynthia has no intentions of letting them join), they must steal a cadaver from the university medical center and place it on the steps of the Phi Omega Gamma house. Chris and J.C. find one in a top secret room that is being kept in a state of suspended animation, but when it grabs one of their arms as they try to move it, they lose their nerve and run back to their dorm room. Meanwhile, Detective Ray Cameron, a cop that dated the girl killed back in 1959 and is haunted by the memories of what he found that night, is called in to the cryogenics lab break-in where there were two bodies, but one is now missing. The missing body is the one released from its cryogenics tomb - the same boy who found the alien experiment back in 1959. This missing body makes its way back to the same sorority house where he picked up his date 27 years earlier. The walking corpse comes to Cynthia's window where his head splits open and more of the leech creatures fall out and slither across the ground. Called to the scene, Ray finds the body with a large open wound in the face, similar to one that could have been made by an axe.

The next day, Chris and J.C. are confronted by the frat brothers, upset over the fact that they believe they are responsible for the previous night's incident. After surviving their encounter, they are then taken in for questioning by the police. Based on the testimony of a janitor that witnessed them running out of university medical center, "screaming like banshees," they confess to breaking in, but deny taking the corpse out. That night, the attendant found dead gets up from his slab and runs into the same janitor.

After the dead and buried cat of one of the sorority sisters comes back, Cynthia confesses it to Chris and J.C. and goes on about the dead body found at the sorority house. Although both are skeptical of her story about them being zombies, J.C. sees that she is leaning on Chris' shoulder, and leaves the two alone to go to the bathroom, where the now-possessed janitor enters and lets loose more of the slugs.

As Chris walks Cynthia back to the sorority house, he runs into Cameron who has overheard the entire story. Back at Ray's home, the two talk about their high school sweethearts. Ray's story is more elaborate as he goes on about how they broke up and he became a cop and how he was called out to the site where she had been hacked up by a lunatic. He goes on to tell of how he tracked down the escaped patient, killed him and buried him in the same spot on which the House Mother's cottage now sits. Just then, Ray gets a call where the House Mother has been hacked up to death by the axe-wielding corpse that broke in through the floor. The killer is finally tracked down and cornered by the police, but numerous gunshots have no effect. Cameron then takes his shotgun and blows its head off, which releases more of the little creeps.

The next night, everyone is getting ready for the formal when Chris notices a tape recorder on which J.C. has recorded a posthumous message to his friend, telling him that one of the things has incubated in his brain and that he had discovered, after lighting one with a match, that heat can destroy them. Chris then runs into the boiler room, where his friend has told him he was headed in an attempt to kill those inside him. Chris then shows up at Ray's place, which Ray has sealed up, and he fills him in. After grabbing his gun and turning off the gas, he takes Chris to a police armory to get a flamethrower. They come to the sorority house just as Cynthia is breaking up with Brad who has become possessed. After killing him, the Delta fraternity brothers show up - despite having been killed in a bus crash. While Chris and Cynthia team up with shotgun and flamethrower to destroy the dead outside, Cameron does likewise inside. After stopping the horde, Chris spots more slugs racing across the ground that are headed into the house's basement. Cynthia remembers that this is where specimen brains are being kept. When they go down below, they find Cameron, tape across his mouth, prepping a can of gasoline. They also find the creatures gathered in a huge swarm in the corner. Cameron begins counting down as he splashes gasoline everywhere. Cynthia and Chris turn and run out of the house, counting down in sync with Cameron. Cameron fills the basement with gas and just as some of the parasites leap at him, he flicks his lighter and the house goes up in a fiery explosion. Watching the sorority house burn, Chris and Cynthia share a kiss. The scene ends when the dog that caused the bus accident returns, opens its mouth, and a slug jumps out.
