When the spaceship Jehad lifted off for Mars, the crew of four men and one women are placed under the rule of Dr. Lewis Spartan, a sadistic, power-hungry leader of the expedition. Only when they are well under way do they realize that Spartan plans to return to Earth by himself. As the Jehad approaches Mars, jealous rivalry amongst the crew leads to tension and strife, totally unaware of what awaits them on the martian surface, a martian threat that could cause their death, but deliverance would mean to yield to Spartan's schemes.
