Spain, 1468: A young king and queen proclaim themselves the Catholic monarchs and start an Inquisition.

Spain, 1468, a land where Christians, Muslims and Jews have lived in tolerance for centuries. But that time is ending. A young king and queen bent on immortality proclaim themselves the Catholic monarchs and start an Inquisition. Jews who had converted to Christianity are accused of secretly sabotaging the Christian faith. They become pawns - with dire consequences. Thousands perish in a ritual called the act of faith. In Zaragossa, the inquisitor is assassinated - setting off a wave of reprisals. Mothers will die to protect their children - and the highest in the land will pay the ultimate price. It is the beginning of the Spanish empire and a long dark night that will last for centuries.
