Revolution has come to Mars. Max Lupine has been secretly creating a virus to pacify and enslave the populace. However, a mining accident triggers a premature release of the virus and sets off a pandemic that causes the majority of the populace to become mindless killers. Beverly Gibson, lead scientist of the Delta Dig, tries to rally a resistance not only to battle the infected that roam the populated living domes of Mars, but to stop Max Lupine from consolidating his despotic power. Beverly is assisted by Edgar Lourdes who is the only man on the planet with the ability to diagnose and combat the virus. He must discover how the virus was created and how to save the millions of people living on Mars. Recently arrived Thomas Stargell must battle across the Martian landscape to find Beverly's resistance group and help them break Max Lupine's control of the communications on Mars. He must attempt to contact Earth and hope they will come to the aid of the beleaguered Martians. When Lupine discovers how to control the infected the stage is set for a final showdown to find out who will control the future of Mars. Beverly's rebels and Lupine's forces meet in a climactic planet wide showdown that will cost many their lives and force the people of Mars to become revolutionaries or find themselves under the control of a madman.
