What could be better than a vacation… with adventures! However, the engineer Vasily Merkuryev, who dreamed so much of cold seas and an autumn forest, doesn’t want any adventures at all!.. But they begin as soon as he arrives at a small seaside hotel. The owner introduces him to the guests: there’s a young student bored out of her mind, a young man plainly longing for something, a woman who looks like she’s out to hunt— and… a young witch. Naturally, Merkuryev doesn’t believe in any witches. And then, as if mocking him, reality starts playing strange jokes: an old book about the life of philosopher Kant seems to be read by someone, the fire in the fireplace flares up by itself, and on a deserted lighthouse—there’s… a murder. Vasily Merkuryev knows for sure that there are no witches, no ghosts, no spirits—yet he keeps running into secret or obvious traces of their presence. Even his love for the young witch—or maybe for someone who isn’t a witch—seems foretold by forces from beyond… Sometimes it’s hard to believe. Even harder is accepting it. But if you allow yourself to believe, life turns out to be full of miracles—real ones, not invented ones!
