The Curse of Dracula - Season 1 (1979)

Mary discovers, to her chagrin, that she bears the mark of Dracula. Van Helsing promises to save her, but Mary finds herself growing increasingly attracted to Dracula, despite the knowledge that he killed her mother.

Von Helsing is kidnapped, leaving Mary to deal with Dracula on her own.

As Mary surrenders herself to Dracula, Van Helsing is rescued from the crypt by a mysterious woman, a vampire herself. Van Helsing is reluctant to ally himself with this creature of the night, until she confesses her hatred for Dracula.

The female vampire who saved Van Helsing is revealed to be Amanda Gibbons, Mary's mother. Amanda attempts to convince Mary that it is better to be human and "moral," than a creature of the night who is enslaved by a never-ending blood-thirst.

Mary is now part-vampire, and Dracula uses that fact to attempt a further seduction. Amanda and Van Helsing do their best to defend Mary from Dracula's grip.

Amanda comes up with a painful ordeal that may free Mary from Dracula's power.

Von Helsing and Mary search for Dracula's coffin hoping to end his existence.
