Never has spookiness been so beautiful. When Lina moves to Villain Street, she immediately senses that something is off. The charming smile of her neighbor is actually a nasty shark grin, and the supposedly nice Edi Ebsbeck can extend his fingers at will and shape them into a key. Luckily, Lina meets the boy Wendelin, who has also noticed that the residents are up to something. Together, the children devise a plan to put a stop to the villains' schemes.
