THE TORTURE CHAMBER OF DR. SADISM

The film is set in the 18th century, and the probable story location is Germany. Baroness Lilian von Brabant and her lawyer Roger Mont Elise receive an invitation to the Blood Castle, in Sander Valley, where a large inheritance is awaiting the Baroness. Both decide to go; the Baroness because of the inheritance and Roger seeing a chance to get more information regarding his birth. Upon arriving at the valley, in separate carriages, they meet the monk Fabian, who has a proclivity for profanities. Fabian offers to assist them in finding their way to the castle, the place where, 35 years ago, Count Regula had murdered 12 virgin maidens, in an attempt to use their blood to achieve immortality. However, he was one maiden short of his goal, and he was drawn, quartered and beheaded for his crime. As he was dying, the Count threatened revenge against those responsible for his death.
On their way to the castle, the lawyer and the monk see the Baroness and her maid Babette being attacked by mysterious hooded riders who try to abduct the women. After Roger fends off the robbers, he offers to let the women ride in his coach. While passing through a dead forest full of corpses, with human limbs and torsos hanging from the dead tree branches, the coach is hijacked with the two women inside. Fabian, who is revealed to be a robber rather than a monk, is so terrified by the unexplained disappearance of the women that he offers to help Roger find them. The two men finally locate the women locked in an iron chamber at Blood Castle, although they get caught before they can rescue them.

After their capture, the Count's evil, green-blooded servant Anatol informs the two men that he is planning to bring the Count back to life after 35 years. Anatol, using his own green blood, finally achieves his goal of reviving the Count. Following his resurrection, the Count appears to the prisoners wearing an iron mask, informing the men that he needs the blood of a thirteenth virgin – the Baroness – to achieve his goal of immortality.
After the pronouncements by the Count, the prisoners make an escape attempt, but they are unsuccessful. As punishment, the Baroness is locked into a snake and spider pit, where she nearly loses her sanity. Roger, imprisoned in a pit with a pendulum, manages to overcome the odds and survive. He also recovers the diamond-encrusted cross of the Baroness, which he uses to destroy the Count and Anatol, finally succeeding in freeing the prisoners. The Baroness recovers and falls into Roger's embrace, while Fabian leaves the crumbling castle with Babette.

Roger uses the Baroness's diamond-encrusted cross to destroy Count Regula and his servant Anatol, freeing the prisoners and escaping as the castle collapses.

The climactic destruction of both Count Regula and his wicked servant with a holy relic closes the cycle of vengeance that haunted the castle for decades. Using the Baroness's cross as a weapon not only saves the protagonists but symbolically overcomes the count’s unholy ambitions. The survivors' escape from the crumbling castle marks closure for the curse-laden Blood Castle while restoring hope to its last victims.
