The supercomputer EXCALIBER has, in four short years, mastered every facet of human lives, frugally parceling out meager resources and shunting individual freedoms. The machine, assuming owning all human destiny and endeavor, has determined to eliminate 90% of the human population, and 99% of her leadership. The computer has uprooted and crippled the last manifestations of capitalist democracies, and subjugates the citizenry with an ambitious global Communist empire and a fanatical Muslim Caliphate.

The last hope for mankind is the 'Messiah', one man who can lead the faithful Christians, Jews, and Muslims, against a soulless machine. The selfless, incorruptible, resolved, zealots of each faith are represented. A Muslim ER doctor and recent mother, a former U.S. President, who is Jewish, and an exceptionally skilled and fearless 'dishonorably discharged' warrior Christian, together with a desperate, scheming man with a personal vendetta, who identifies as the 'AntiChrist', characterize the full, varied human front opposing EXCALIBER. Can the lone 'Messiah', together with the billions who uphold and believe in him prove victorious over the supercomputer?

The day is set for Christ's return. The opponent is formidable and relentless, having not once been defeated. As the Christians, Jews, and Muslims overcome their prolonged differences and assemble for the Last Battle, in the valley of Meggido, the 'Messiah', a man the computer has no data on, must emerge and swiftly and completely meet EXCALIBER's prowess and challenge and defeat it. Can the 'Messiah', together with the best of mankind, end the computer's reign and save humanity?
