Special Prosecutor Kamil Pasha is called in to investigate. He soon encounters his most ruthless adversary to date: Vahid, head of a special branch of the secret police, who has convinced the sultan that the commune is leading a secessionist movement and should be destroyed - along with surrounding villages. Kamil must stop the massacre, but he finds himself on the wrong side of the law, framed for murder and accused of treason, his family and the woman he loves threatened.
