MPAA rating: PG-13, for crude and sexual humor, and sci-fi action. It all starts with a meteorite falling to earth near Glen Canyon, Arizona. The next day, biology teacher Dr. Ira Kane and geology teacher Harry Block from Glen Canyon Community College go to investigate. While taking a sample, they discover a slimy blue fluid oozing from the meteorite. Kane finds myriad single-celled life-forms in the fluid, evolving at an incredible rate, even while he's watching. What seemed like a sure ticket to Sweden for the Nobel Prize soon develops into a nightmare: by evolving and adapting at an unbelievably fast rate, the aliens start spreading out, and the military comes in. Will humanity save the day?
