The Wünschmann family isn’t exactly a happy family. Mother Emma encourages the family to put their differences aside by taking them to a theme park. After a harmless joke with a doll, which turns out to be the evil witch Babayaga, the Wünschmanns are transformed into monsters. Mother Emma turns into a vampire, dad Frank becomes Frankenstein, daughter Fee turns into a mummy, and son Max winds up being a werewolf! And that’s when a normal ride on a ghost train turns into a ludicrously spooky adventure. Will the Wünschmann family find their happy ending?
