'A storm is raging around the forests of Transylvania, where siblings Anna and Max are visiting with the Professor. Left alone to explore a creepy old inn, the children discover that something evil is lurking in the trees – and it just might have a taste for human blood.

'When Max goes missing, it’s up to Anna and her new friend Isabella to rescue him. Setting out in the dead of night, with the storm howling around them, the girls will face peril after peril. Only one thing is certain: even if Anna can find a way to rescue her brother, Max will never be the same again.' (Synopsis)
