A team of brave soldiers journey into the deepest reaches of outer space on a mission to unleash a virus that will devastate the alien species that seeks to wipe out all of humanity in director Phillip Hudson's low-budget sci-fi thriller. The year is 3037. A race of aliens with powerful psychic abilities is determined to make mankind a distant memory. In a last ditch effort to combat the otherworldly menace, a military strike team is dispatched to the alien's home planet armed with a powerful virus that's been engineered to directly attack the immune system of the hostile alien foe. Should the mission prove a success, the alien race will be exterminated and the threat to humanity neutralized. When the team crash lands on the alien planet and the captain suffers critical injuries, however, it's up to the inexperienced Lieutenant Gray to take control of the mission and deliver the payload. But this Homeworld harbors a deadly secret that leaves the soldiers unable to distinguish truth from illusion, a fact that could prove fatal for the entire human species.
Além disso, o trailer oficial mostra que o filme acontece em um ambiente de selva / floresta e 1 : 09 e 1:38 você pode ver alguns crescimentos de cristais verdes.
