The young Romanian prince Flanders Dracula (Rudolf Martin) and his brother Redu were kidnapped by the Turkish Sultan as hostages. At the same time, their father was murdered, but the murderer was never found. After being imprisoned for many years, Dracula was finally released. He came to Hungary and asked King Janos for help. In the Hungarian court, he met the daughter of a nobleman, Lydia (Jane March). The two fell in love and got married soon after. When Dracula returned to Romania, he was warmly welcomed by the people. However, in order to consolidate his power, Dracula began to slaughter many criminals, corrupt nobles and priests, and nailed them to stakes for public display. Lydia heard rumors about her husband's atrocities, but Dracula comforted her and concealed the truth. Dracula declared war on Turkey and sneaked into the enemy camp in person, attempting to assassinate the Sultan, but failed and returned seriously injured. At this time, Lydia, who was in seclusion, began to be disturbed by the ghosts killed by Dracula. When she saw Dracula return, she mistakenly thought he was a ghost, so she jumped from the tower and fell to her death. Her body has never been found, and she has become an "immortal ghost". Dracula's brother Redu surrendered to the Turkish Sultan. He was jealous and wanted to kill Dracula. He led the Turkish army to attack Romania. At this time, Dracula accidentally discovered the real murderer who killed his father. In the process of seeking revenge, he was expelled from the church. In the end, he finally died at the hands of Redu and became an "immortal" like Lydia.
