A musical comedy about the adventures of four friends who are trying to film a yogurt commercials.

The setting for this off-beat drama of love and jealousy is the Pushkin Poetry Festival in Boldino. Liosha and his wife Tania are walking through the plush forest around Boldino when a mysterious figure pops up from behind a tree and asks the couple a question on an esoteric point of Pushkin scholarship. From that strange beginning, the man, whose name is Klimov, starts to ease himself into the couple's private space, and trouble ensues. Complementing this story is the festival itself, enactments of Pushkin's works, and emotional debates among the festival-goers over the meaning of his poetry.

Based on one of Turgenev's Hunter's Sketches: the Lone Wolf of the title is a forest caretaker for a flippant aristocrat. Though he lives in absolute misery in a hut deep in the woods with two small children to take care of, he's feared for his merciless stalking of the starving serfs who sneak in to cut firewood.
