In the shadowed peaks of eastern Europe, an ancient vampire known as the Immortal Lord awakens once every hundred years, drawing forth horrific beings from the crumbling remains of his fortress to herald his return. When a local nobleman witnesses these ominous signs manifesting across his lands, he desperately summons the region's renowned demon-hunting clan to confront the resurrection. To his surprise and dismay, only a single warrior arrives—a young woman dressed as a maid, wielding nothing but a morning star as her weapon. What unfolds is an unlikely confrontation between this diminutive but determined fighter and one of history's most powerful supernatural threats.
