The two twelve year old half-vampire sisters Silvania and Dakaria Tepes move from Transylvania to a small German town, together with their father Mihai (a vampire) and their mother Elvira (a human).

Meanwhile, Silvania can't spend time with Jacob at the pool because of her sensitivity to the sun.

By chance, they discover the shop of Ali bin Schick, who can grant them their hearts' desires.

After they make their wishes, there are numerous complications: Silvania wants to drink Jacob's blood, while Dakaria is unable to defend herself from the school's bullies.

[3] A sequel, titled Vampire Sisters 2: Bats in the Belly (Die Vampirschwestern 2 - Bats in the belly), was released in October 2014 in German cinemas,[4] but didn't land in Dutch cinemas until July 2016.
