Tertiary student Vasia Vasylkov receives the keys to the museum of various arts for one night from the watchman. The main requirement is that all exhibits must be in their places in the morning. But the main character, of course, does not obey the watchman's instructions, so he plunges into a whirlwind of magical adventures, meeting ghosts, Casanova, Assol, Dracula, Sleeping Beauty, Romeo, Red Riding Hood, and Snow Queen.
