After crash-landing on a desert planet, astronaut and forensic anthropologist Gav Torres becomes separated from the rest of his expedition. He soon enough reunites with everybody except one person: his fiancé, Shelley Wu. Gav's persistence to find Shelley will soon reveal to him the alien terror from beyond death that may be responsible for her disappearance, the previous expeditions' disappearances and the likely annihilation of himself and the rest of the current expedition.
