Best friends Venus, Rochelle and Robecca continue not only to study at the most disgusting school - the school of monsters, but also to investigate mysterious incidents. It is unknown where white cats appeared in the educational institution, which for monsters are the same harbingers of misfortune as black ones for ordinary people. Someone painted the walls with ominous threats and began throwing warning notes. Is this really the work of the evil Miss Podletysh, who once already tried to subjugate all the students of the school of monsters? The friends must get to the bottom of the truth at all costs.
