The rain is different from any rain Vivian has ever experienced. It doesn’t take long for her to figure out that it wasn’t only different, but deadly as well. Something in the rain changes people into raging maniacs, programmed to kill.
If that wasn’t bad enough, it doesn’t take Vivian long to discover the rain alters not only humans unlucky enough to get caught in it, it also changes flora and fauna.
Soon, a new plant emerges, a plant unlike anything on Earth. It is not only carnivorous, but it also raises the temperatures in its vicinity to uninhabitable levels.
When Vivian and her friends discover that the plant is only the beginning of an alien plan to transform Earth, they face an impossible battle. As Earth’s last hope to defeat the aliens and return our planet to its natural state. With the odds stacked against them, will they be able to save humanity?
