A colony on Mars comes under attack from a gang of humanoids and a murderous alien in this witty, low-budget sci-fi comedy. The saga takes place years in the future, when bureaucratic workers comprise the base of the planet's work force. Stranded millions of miles from home and bored to tears by their corporate jobs, the nine hapless office drones discover a mysterious fossil that leads them to believe their once may have been life on Mars. Before they have time to study the artifact, however, their base is invaded by a horde of rampaging outsiders and a powerful extraterrestrial intent on wiping everyone out. Meanwhile, as their employees fight for survival, Interplanetary Corporation attempts to suppress word of the attack from reaching consumers for fear that their stock prices will take a heavy hit.
