Alien Hunter begins in the 1940's. A radio operator receives a bizarre signal from Roswell. His curiosity gets the better of him, and he sets off to find the signal's source, never to be seen again. The timeline then jumps to present day; the same signal is coming from the South Pole, and it eventually reaches the United States. A satellite image shows an unknown object atop Antarctic snow. Julien Rome, a cryptologist, is invited to investigate this mystery and is sent to a research base in Antarctica. Rome and the scientists soon discover a pod-shaped craft held within a mass of ice. The craft makes the same encrypted signal as before. Once the scientists manage to dislodge the craft, Rome realizes that it has an electrical defense field that painfully shocks anyone who touches the craft. While Rome is busy decrypting the signal, another team tries to open the craft. This team eventually removes the lid, allowing a slimy fluid to gush out. At the same time, an alien creature escapes right when an airborne virus is released from the craft, melting four members of the science team and killing all the plants in the base's greenhouse. The virus is determined to be a massive biohazard, killing anything exposed to it within minutes. The government requests a Russian submarine to launch a nuclear projectile against the base. As the submarine reaches its destination, Rome communicates with the creature. One of the survivors kills it. Rome understands that the survivors must be quarantined. Anyone could spread the virus. Just as the projectile is about to hit, Rome and three others are saved by an alien ship that had homed in on the encrypted signal. In the end, the government blames everything on an "experimental reactor." The final scene of the film shows the spacecraft leaving the solar system, with the human survivors still on board.
