1941, German High Command receive a distress call from a Captain Klaus Woermann, who is stationed at a Keep in the Transylvanian alps, which reads ‘Request Immediate Relocation. Something Is Murdering My Men.’ SS Commander Erich Kaempffer is sent to investigate.
A week earlier, Woermann and his men arrive in the Transylvanian Alps, Romania, where they take refuge in a strange Keep. They are warned by a family keeping maintenance of the Keep not to stay but they do not heed they’re warning. Woermann notices the Keep walls are littered with strange crosses.
The first night, in the cellar, a guard on watch decides to try and deface one of the crosses in hopes to find riches behind. He and another manage to remove the cross to find a small passageway behind and one of them enters. After he starts to contort violently after feeling very cold, he is pulled back out by his comrade who finds his head has been ripped off. Something has escaped through the passageway.
Far away, a stranger awakes suddenly and gets ready to set sail to the Romania and The Keep.
Several nights go by and there is a ghastly murder per night despite Woermann’s efforts to catch the elusive murderer. He then sends out message asking High Command for help after witnessing one of the murders himself.
We are introduced to Theodore Cuza and his daughter, Magda, who both live elsewhere in Romania, preparing to move location in order to avoid the Nazi plight.
Kaempffer arrives with his SS troops and starts to interrogate the local villagers around the Keep. Woermann knows that it wasn’t one of the villagers. Whatever the killer was, it was able to kill and escape without being seen.
The mysterious stranger nears the Keep by sea.

After being unable to do so, one of them advises the Woermann about an old philosopher and professor by the name of Theodore Cuza, who they think will be helpful in finding out what might be killing the german soldiers.
German soldiers arrive a the Cuza household and force both Theodore and Magda to come with them to the Keep.
Theodore and Magda Cuza arrive at the Keep, where Theodore is set straight to work on interpreting what the killer might be. Not far away, the stranger approaches by bike, dealing with several german-patrolled road blocks on his way.

EPISODE III - ULTIMATUM
EPISODE IV - ANNIHILATION
The stranger arrives in the village surrounding the Keep and takes refuge in a small room for rent.
Magda finds Theorfore, who has become several decades younger. He explains to her that the demon, Molasar was responsible and wishes to help him so that he might help them.
After visiting the village, Magda comes across the Stranger, named Glakken, who presses her for information on the occurrences within the Keep. He explains that the demon, Molasar, has has escaped from his prison within the Keep and that he, himself, had sealed Molasar away many years ago. He had awaited the day in which Molasar would inevitably be released and had come to seal him away again, if not destroy him completely.
In the Keep, a semi-formed Molasar confronts Theodore. He explains that he needs to go into the depths of the Keep and retrieve a key which will disable the final bonds on prison and he will be free as Molasar is unable to retrieve it himself. In order to convince Theodore, Molasar promises that he will seek out and destroy the Nazi empire if he does this, which Theodore blindly agrees to.
Theodore then goes into the village in search for Magda, who he finds has become romantically involved with Glakken. Glakken tries to warn Theodore not to help Molasar escape as he would bring nothing but destruction. Theodore feels threatened by Glakken and proceeds to report him to Woermann and Kaempffer, accusing him of the murders of the german soldiers.
Glakken is being brought in by several german soldiers when he puts up a fight and is shot, seemingly fatally wounded, and falls into the river which surrounds the Keep.
Theodore sets off in search for the key which will ultimately free Molasar from the Keep.
Tensions start to grow between Woermann and Kaempffer. A massacre ensues when Molasar starts to systematically kill off every german soldier in the Keep. After retreating to Woermann’s quarters, Woermann starts to reflect on the futility of the Nazi ideology, stating that this is punishment for the war crimes the Nazis have been committing during the Second World War. Enraged, Kaempffer shoots the traitorous Woermann, killing him.
After heading back into the main Keep grounds, Kaempffer finds a a bed of mutilated corpses that where his own men along with rest of the german soldiers. He is then confronted by a now fully-formed Molasar. After pleading with Molasar, asking what he was, he is answered with ‘I am from you…’ before being killed.
Theodore returns, along with Magda, having found the key. Molasar orders that Theodore gives him the key. Theodore then realises his error works out that all Molasar would bring is destruction under his own rule, and that he was imprisoned for a reason. Therefore he refuses. Molasar attacks Theodore, returning him to his aged, weakened state.
Before Molasar is able to kill Magda, Glakken appears at the Keep entrance, fully recovered from his wounds and brandishing a sword which he had brought on his journey.
A climactic battle ensues.
Glakken is then able to return Molasar back to his imprisoned state, sealing back inside the Keep forever. Glakken then is reunited with Magda and they and Theodore leave the Keep together.
