Een groep Nazi's krijgt de opdracht om een oud en mysterieus fort in een Roemeens gebergte te bewaken. Een van hen bevrijdt per ongeluk de kwade kracht die zat verborgen in de oude muren van het fort. Een mysterieuze vreemdeling uit Griekenland voelt dit aan en vertrekt naar het fort om de kwade kracht te stoppen.
