It's summer vacation. A summer vacation that brings together twelve-year-olds Alexandra, Dushan, Tindra and Edvin. Usually they hang out with completely different friends. But now it is only those who are not gone and the four agree on a revenge against the mythical Foil Man. His windows are covered with foil and rumor has it that he kills cats, puts them in the freezer and buries them in an animal cemetery in the woods.
