When his space ship crashes and nearly kills him, Jasons injuries cause him to lose his sight. He stumbles around on the alien planet until he encounters Reyna, an advance female android who has been living on the planet. With the aid of an audio motion sensor, Reyna teaches Jason how to defend himself against monsters andwhat he believes to be enemy soldiers. Eventually Jason learns that Reyna is not just protecting him but trying to keep him prisoner because his presence reactivated her power source. If he leaves she will shut down again. She is willing to do anything to keep him there, including killing his colleagues who came to rescue him.
