In a battle-ravaged land where power is concentrated in the hands of warlords known as Thanes, society is held together by unwavering loyalty to the king. But outside the clan system and the heavily fortified strongholds of the Thanes, strange rituals and satanic cults chip away at the status quo.

Noble Macbeth, one of the most powerful Thanes, is seduced by this witchcraft. He and his wife, shattered by the recent loss of a child, seek to fill the void with power. They hatch a plan to murder the king, unleashing a cycle of violence that destroys everything they prize: loyalty, security, friendship, peace of mind, their love for each other and ultimately their souls.
