Dawn of the Death Rite

On a blizzard-ravaged Christmas Eve, a troupe of young actors is invited to the baroque theater run by the enigmatic Heisenhof family to rehearse the reclusive playwright's magnum opus. When a killer wearing an eyeball mask appears, rehearsal turns into a brutal survival contest. The actors belatedly realize that every death scene in the script is part of an ancient ritual meant to summon the Antichrist.
