On the mountains in Western Maryland a large chemical company has been dumping its waste in the woods. Now a strange thing has happened. The trees have been attacking hikers! The company sends in two mercenary convicts to deal with the problem, but things don't go well. The plot thickens as a college professor takes a group of students out onto the mountain to look for the elusive "goatman" that is believed to be responsible for the attacks. Along the way they meet a strange cast of characters and soon find that they are all now being hunted by the killer shrubbery. They have a particular taste for the lovely flesh of the ladies. Will any of them make it out alive or is mankind doomed to become food for the foliage!!!!
