The world is in chaos and the West is either powerless or unwilling to stand up to the jihad. Iran spawns a burgeoning Caliphate arming themselves with nuclear weapons through research, theft and alliances. Yet not everyone in the Islamic world is ready to have the Iranians lead them. Enter the Mahdi. The mythical Mahdi, the leader who will establish Islam's eternal Caliphate over the world, comes to Tehran. The mere rumor of his coming sends the Islamic world into insane fury, for the Mahdi can only be called by blood. The jihad invades Israel; the USS Enterprise, the symbol of Western power, is trapped in the Suez Canal; jihadists storm Paris; and in the United States Islamic enclaves invoke Sharia law. The West appears powerless to stop the onslaught. In desperation Flint Wolfe, the infamous "Crusader" is resurrected for one last fight. Wolfe must find a way to prevent the nuclear Caliphate from immolating the world under the evil auspices of the Mahdi . . .
