The Keep

Two cousins, irreversibly damaged by a childhood prank, reunite twenty years later to renovate a medieval castle in Eastern Europe. In an environment of extreme paranoia, cut off from the outside world, the men reenact the signal event of their youth, with even more catastrophic results. And as the full horror of their predicament unfolds, a prisoner, in jail for an unnamed crime, recounts an unforgettable story that seamlessly brings the crimes of the past and present into piercing relation.
