A group of scientists, employed by a company called Earth Tech, work on dangerous experiments five miles beneath the surface of the planet. One of them, drug-addicted 'Brainiac' has created a virus for the military that will create the ultimate soldier. Things get out of hand when an infected lab rat escapes, which consumes and incorporates each host into its genetic structure. So, by the end of the movie we have a monster that's part rat, part cat, part human. Although very clearly ALIEN inspired it is very watcheable due to the performances--in a goofy scene the first person infected has a spasm on the breakfast table, only instead of a 'chest-burster' this creature explodes out of the guy's back and through the table!
