Not Like Others (2008)

While escaping from the bikers, Vanja gets more determined that she wants to leave the outcast vampire-lifestyle and adjust to the human world. She wants to live a normal life, even though it means the end of a life together with her sister. Vera won't accept a life in solitude and is willing to fight to make her sister stay.
