在这部魔羯出笼恐怖片中,在温室里工作的时候，一个人在接触了一种外来植物后，就会受到昆虫的叮咬。很快，他病倒了，被送到了急诊室，医生诊断他患有未知的细菌，还有一种奇怪的寄生虫，从他的嘴里冒出来，像一个巨大的泥虫一样。很快，细菌感染的病例增多了，但更直接的问题是，在意外暴露于基因生长刺激物后，这种虫状生物生长得越来越严重，在医院里开始了一场恐怖和流血的统治。
While working in a greenhouse, a man receives an insect bite after touching an exotic plant. Immediately, he falls ill and is taken to an emergency room where the doctors diagnose him as suffering from an unknown bacteria, and a strange parasite which emerges from his mouth as a large slimy wormlike creature. Soon, there are more cases of bacterial infection, but the more immediate problem for the hospital is the wormlike creature which after accidental exposure to a genetic growth stimulant grows to monstrous proportions and starts a reign of terror and bloodshed in the hospitals abandoned wing.
