Another wave of crime breaks the peaceful tranquility of the animals in the Far Forest. First, they rob an underground art exhibition, and soon after, they kidnap Márkíz, the pampered, snow-white Persian cat, from the cat exhibition. All clues point to the Arctic Fox being the culprit - until a group of mixed animals called Harag Klaws appears, who want to take revenge on purebred, well-fed, happy and lucky animals. Can Big Badger and Badgercat find the members of the Wrath before they strike again? Will Badger be able to put aside his growing feelings for the Marquis and maintain his sense of duty as a professional officer of the Far Forest? And what is the mysterious, naked animal up to? Who could he be?* * *

In the fourth part of Animal Detectives, Főborz is faced with his strangest case so far: in the Far Forest, someone is tearing and burning the feathers of birds. To make matters worse, the prime suspect is his former assistant, Badger. Főborz knows that his old companion cannot be the Plunderer, but then who tore up Ms. Kakukk and attacked the owl twins, Ukk and Mukko? Maybe Master Sickle Swallow was the hairdresser who was obsessed with fur and feathers? Or the cunning, treacherous Arctic Fox? Maybe the compulsive thief Quick Lizard? Or someone else?
