In 1887 Transylvania, Doctor Victor Frankenstein creates a monster with the anticipated aid of Count Dracula, who reveals that he plans to use the creature for his own evil plans and kills the doctor as his castle is raided by a mob of villagers. His assistant Igor escapes, but the villagers chase the monster to an old windmill and set it ablaze. The villagers are scared off by Dracula and his brides, who witness the monster and the doctor's research apparently destroyed by the fire.One year later, after killing the elusive Mr. Hyde at the Notre-Dame Cathedral in Paris, monster hunter Van Helsing returns to the Vatican in Rome. He learns his mission to destroy Dracula and his amnesia are penance for past, unremembered sins that cause nightmares. He is tasked with helping the last of an ancient Romanian bloodline, Velkan Valerious and his sister Anna, who must kill Dracula before their ancestors may enter Heaven. Carl, a friar provides Van Helsing with aid and weapons. Meanwhile, in Transylvania, Velkan is apparently killed during an attempt to trap and kill a werewolf, and Anna is attacked by Dracula's brides shortly after Van Helsing's arrival. He saves her life and kills Marishka, one of the brides, but as the last of her line Anna becomes more determined to kill Dracula. In order to protect her, Van Helsing knocks her out to prevent her from leaving. Later that night, she awakens and encounters Velkan, who reveals Dracula has a dark secret, but to her horror, he becomes a werewolf and attacks. After she and Van Helsing track him to Frankenstein's castle, they discover that the vampires are attempting to give life to their born-dead children, using Velkan as the source of the power. Van Helsing, dubbed "Gabriel" by Dracula, realizes they had ties in the past. Van Helsing refuses Dracula's offer to return his memory and escapes. The experiment fails however, and the vampire children die, but Velkan turns on Anna as he becomes completely consumed by his curse. The pair then escape together.Under the remains...
