Velma získa po prastrýkovi zámok. Partia ju presvedčí, aby sa šla na dedičstvo pozrieť. Zámocký duch ich však varuje, že vyhodí do vzduchu stroj záhad.

Vampire sisters Silvania and Daka try to rescue their baby brother, a half-vampire, from the clutches of the evil vampire queen Antanasia, who wants to crown him as her heir.

Keeping secrets can be difficult, especially when you’re a twelve-year-old half-vampire moving from Transylvania to a new life in Germany. Going to school, making new friends and fitting in — it’s all tough when you can’t just be yourself. With a vampire father and a human mother, sisters Dakaria (Daka) and Silvania don’t live in your typical blended family. Each girl embraces a different side of her genetic makeup: Daka wishes she was 100% vampire; Silvania wishes she was 100% human; and both believe they can finally realize their hearts’ desires when the opportunity to change presents itself. Will Daka and Silvania realize that, sometimes, your uniqueness is your greatest strength?
