Description
Two huge interplanetary ships on an expedition into deep uncharted space receive a distress signal emanating from Aura, an unexplored planet. Both ships, the Galliott and the Argos, attempt to land on the surface of the fog-encased world. While entering the planet's atmosphere, the crew of the Argos becomes possessed by an unknown force and try to violently kill each other. Only Captain Markary has the will to resist, and is able to force all of the others aboard his ship out of their hypnotic, murderous state. After the Argos lands on the surface, the crew disembarks and explores the eerie landscape in search of the Galliott. Thick, pulsating mists, lit by ever-shifting eerie colors, saturate the terrain. When they finally arrive at the other ship, they find that the crew members have killed each other. Markary's younger brother, Toby, is among the dead. They proceed to bury as many of the corpses as they can, but several bodies are locked inside the ship's bridge. Markary departs to get tools for opening the sealed room, but the corpses disappear by the time he returns.
Some of the Argos' crew are found dead. Tiona sees their corpses walking in the ship, and becomes paralyzed with fear. Markary advises the survivors that they must escape from Aura. Unfortunately, the Argos incurred serious damage during the landing, and repairs will take time. During the waiting period that ensues, several more killings occur. In a private tape recording, Markary admits that he suspects none of them will survive. While exploring Aura, Wes discovers the ruins of a spaceship a few miles from the Argos. Markary, Sanya and Carter investigate. Inside the ship, they discover large skeletal remains of the long dead crew and thus realize that they are not the first ones to have been drawn to the planet by the distress beacon. Markary and Sanya are temporarily trapped inside the ship, but manage to escape and return to the Argos. Carter inexplicably vanishes.
Two crew members of the Galliott, Kier and Sallis, arrive at the Argos to steal the ship's Meteor Rejector device. Kier escapes with the machine, but Markary fights Sallis. Markary tears open Sallis' uniform, exposing his putrescent body. He learns that Sallis' corpse is being manipulated by an Auran, who reveals that the two ships were lured to the planet in order for the Aurans to escape from their dying world. With the crew of the Galliott under their complete control, they plan to use the ship to escape to the humans' home planet. Markary vows to stop them. Markary and his crew rush to the Galliott to retrieve the Meteor Rejector. They are successful, and manage to place explosives in the ship. During a struggle with the Aurans, Dr. Karan and Tiona are killed. Markary and Sanya return to the Argos and manage to escape as the Galliott is destroyed. After takeoff, however, they reveal themselves to be possessed by Aurans. They ask Wes, the last survivor, to join them. Wes refuses and tries to sabotage the Meteor Rejector, but fatally electrocutes himself while doing so. Because the device has been broken beyond repair, Markary and Sanya decide to change course for a nearby planet: Earth.
