context: The movie begins in the year 2032, when an expedition on Mars finds a buried egg that they take to the ship. The egg hatches, revealing a crystal and (presumably) a slimy creature that hides on the ship. After the astronauts decided to use the crystal on a large laser cannon, they all die when their air supply runs out.
  Two months later another expedition comes on board, but they end up stranded when their shuttle explodes. When they start to explore the ship (in order to repair it and survive until rescue comes), a mysterious creature starts to kill them all and takes control of the ship. Eventually, with only two crew members alive, the creature reveals itself: its name is GAR, and his crystal is an advanced alien computer. By hacking into the ship's computer Bernice, it learned the English language, the history of human evolution, and read an electronic bible. It discovers the humans are not as belligerent as it first thought - it explains that the deaths were just misunderstandings, as it believed it fought in self-defense the whole time. GAR begs for forgiveness and relinquishes control of the ship to the surviving humans. The two species manage to peacefully co-exist on board until a space anomaly occurs. GAR sorrowfully realizes that he must part ways with the humans, promising that he is grateful for their brief friendship and that he will never forget them. The film concludes with "Crystal of a Star," sung by Stefani Christopherson.
