The stones guard an ancient secret. And some secrets are buried in blood.

Dr. Eleanor Vale’s controversial theory about Stonehenge could rewrite history. But her expedition to the desolate Salisbury Plain uncovers more than she bargained for. Beyond the eerie hum of energies and anomalous magnetic pulses, a primal terror stirs.

Claw marks tear through ancient sarsen. Strange, coarse hairs cling to impossible heights. A team member is snatched by the mist, leaving only a horrifying image on a shattered camera. The local legends of a monstrous guardian, a ‘Keeper Between Stones,’ prove terrifyingly real – a creature of nightmare some might call Bigfoot, but whose true nature is far more ancient and terrible.

As a violent storm isolates them, and the stone circle awakens with malevolent energy, the remaining survivors face a desperate battle. The Keeper is not just a beast; it's a god, a priest of forgotten rituals, and the blood in the circle demands a sacrifice.

Dr. Vale must confront the living horror her theories only hinted at. Can she unlock the final, terrifying mystery of Stonehenge and seal the gateway before the ancient darkness consumes them all?

If you crave relentless cryptid horror, ancient mysteries, and tales of expeditions gone terribly wrong, then journey into the heart of prehistoric terror. But be warned: some legends are true, and some truths can kill.
