Agent Rain Moss (EmmaRain Welling) and her team are sent by agent Tom Mason (Tom Sizemore) to retrieve an antidote to save Europe from a zombie outbreak. Meanwhile, a giant comet is headed to earth and Agent Moss and her team are soon redirected by "The Colonel" (Lee Majors) to save the planet from intergalactic war. Just days after a gun down of zombies, Rain Moss and her older sister Jackie Moss (Alexis Arnold) along with her team return home to encounter aliens believed to be instructed to terraform the earth. Together Moss and her team fight the Russians and prevent the "higher ups" in U.S. government intelligence from starting an intergalactic war with "friendly" aliens, meanwhile running from the local, more than tough town Sheriff, Sheriff Ed Chance (Joshua Peri). Soon the mothership lands and intergalactic peace is restored - for now.
