A U.S. satellite falls to Earth in Piedmont, a small town in Utah. When civilians decide to open up the satellite a mysterious plague is unleashed that kills virtually everyone who comes into contact with it, often driving them into acts of mad violence before they die. As the army quarantines the area, a team of medical specialists is assembled to stop the spread of the pathogen, code-named “Andromeda.”
Three of the scientists gear up in biohazard suits and inspect the town. They discover two survivors – an unhealthy old man and a colicky infant – and take them, the satellite and samples of Andromeda to “Wildfire,” a secret underground lab designed for a crisis of this nature.
As the scientists race to decode and find what kills Andromeda, it continues to spread and mutate. A reporter sees a government conspiracy is afoot and investigates, only to discover that murderous forces want him silenced.
