Fate presents three friends Zhanna, Katya and Irina with a new surprise: having gathered to quietly and peacefully relax in nature and enjoy the beauty of the autumn forest, they find themselves witnessing a murder. Of course, it all starts with the restless Katya, who always sticks her nose anywhere. And thanks to her carelessness, they also showed up in front of the criminal! And now the killer is pursuing them, trying to quietly neutralize the witnesses. Irina is presented with poisoned coffee, the brakes in Zhanna's car fail, a three-pound figure of a rhinoceros falls on poor Katya's head... But if you chase three hares... well, you'll break your teeth. And our friends are not from the timid breed and know very well that the best method of defense is attack.
