1989. Two intelligence agents - Roberto Diaz and his partner Trini Romano - are sent on a mission to Australia. In the local community, after falling there, the debris of the space satellite began pestilence. It turns out that a fungus has settled there - a mutant called Cordyceps novus. It not only parasitizes, but also changes the behavior of the infected. A sample of the fungus is eventually hidden in an underground storage facility in the United States, but later the bunker will be privatized and converted into a regular warehouse in 2019. "Alien" breaks out, and in its path are living things. It is unclear who got infected and who is lucky so far. Roberto Diaz and Trini Romano are back in line. So the big question is: who is who?
