Glen Canyon, Arizona, the present day. The impact of a meteorite changes the life of biology teacher Dr. Ira Kane and geology teacher Harry Block from Glen Canyon Community College when he manages to take a sample. Soon, he discovers a slimy blue fluid coming out of the meteorite. Shortly after, he realises that cells within the meteorite evolve at an incredible rate. What appears to be a sure thing for the Nobel Prize soon develops into a nightmare: By evolving and adapting at that unbelievably fast rate, the aliens start spreading out, leading to destruction and the involvement of the military.
