In the future all sex will be simulated; at least that's the premise of Alien Intruder (1992). It tells of a rescue mission by a group of convicts to save the crew of a space ship where one astronaut went astro-nuts and started shooting up people. To pass time on the voyage there is a virtual-reality sex program that allows the crew to get it on with buxom blonde Melinda Armstrong and brunette beauty Gwen Somers. Trouble is a virus has corrupted the software in the alluring form of Tracy Scoggins, who works to pit crewmember against crewmember. Houston, we have a boner!
