 1668. The jihad is in its heat in the Southeastern Europe. A corps of janissaries is commissioned to the Rhodope Mountains under the command of Karaibrahim. At the time, he was, as all the janissaries were, kidnapped from his Bulgarian family, raised as a Muslim, trained to be a ferocious warrior and convert infidels to Islam in a most brutal way. His cruelty stuns even local Ottoman ruler. He stops at nothing but the resistance of some of the locals is invincible. The struggle is half a success, there are many converts, the death toll is heavy, but all the Bulgarian keep their language and traditions on.
