An extraterrestrial virus attacks all life on earth, crossing the species barrier and confounding the best scientists at the CDC. The virus quickly gets out of control, and only one man, Dr. Tony Van Lee, stands in its way. Hoping to find a cure, he and a small group flee to an abandoned government lab. But he is being hunted by the army's ultra secret bioweapons unit and a violent religious zealot. Without a cure, all of mankind will be lost. The clock is ticking. "Is this the way life ends on earth?"
