A cheeky fox cub encounters a forester, who's drinking beer with the priest and schoolmaster at Pasek's kiosk. Although they come from very different »worlds«, they both sense in the other the chance for their lives to take on a new direction: the forester feels protective towards the impetuous young cub, who awakens memories of his own youth and long surpressed desires, she feels she can trust the older man and hopes for a better life that the one she's known until now. The vixen follows the forester home. Once there she throws the already troubled family totally off balance. Tolerated relunctantly by the forester's wife, and provoked by their sons, it's impossible for the vixen to fit in with the rules of the house. When she wakes up in the forester's bedroom – after a nightmare in which she killed a dictatorial cock – and her first period starts, the forester's wife's patience begins to wear thin. The forester, at his wife's bidding, threatens her, but he's torn between asserting his role as head of the household and his feelings for the wild creature, who takes the forester's knife and runs back to her block of flats. ACT 2 The vixen rudely drives a priest, ridden with phobias about women, from his flat. The forester tries to return to everyday life and forget the vixen and his dreams. After another evening with the Paseks, the schoolmaster surrenders to his dream of the unattainable Terynka, and the priest remembers that, long ago, he was wrongfully accused of raping a young girl. The forester, thinking he's seen the vixen, fires two shots. The vixen meets a fox called Golden Mane. It's love at first sight. She's pregnant in next to no time. The next step's obvious to the fox: »We'll get married!« ACT 3 The woodman Haraschta teases the increasingly introverted forester about the fact that he's going to marry desirable Terynka, and shows him his wedding gift: a necklace. This doesn't stop the philanderer from flirting outrageously with Mrs Pasek. Haraschta says that he's seen a dead hare, which he left where he found it, to be on the safe side. Young fox cubs romp around near the dead hare with the vixen and her husband. They laugh at a trap that's been set and find the necklace, which Haraschta forget about during his short »intermezzo« with Mrs Pasek. He comes back to look for his wedding gift, which is now hanging round the vixen's neck. While wrangling over the necklace Haraschta steps in the trap; the vixen's stolen knife now comes into play; and the woodman stabs her. In panic, he tries to cover his traces. Mrs Pasek, who saw everything, holds her tongue and covers for Haraschta. She and the schoolmaster notice that the forester seems to be getting even odder. Unable to get the vixen out of his mind, he intends to leave his former life and conventions behind him: his first step towards freedom. The acknowledgement of his own dreams and instincts makes it clear that the »flimsy« curtain between different levels of reality – dreams, memories, fantasies … – can lift, making a new dimension visible which, until now, was the preserve of inconspicuous creatures like crickets, grasshoppers and frogs. For the forester these are no longer mute creatures in another, hidden world.
