When a golf ball strikes a frog residing in a city park, the creature transforms into a beautiful woman Vasilisa. Ivan, pressured by his wealthy father to get married, seizes the opportunity and presents Vasilisa as his girlfriend. Vasilisa revels in her newfound human life, but as twilight descends, she reverts to her frog form. It is revealed that Vasilisa was cursed by an evil magician. To break the spell and become human once more, she must receive a kiss of genuine love.

After meeting a vampire, the Shilov brothers discover superpowers in themselves. Sergey and Lyokha learn that in the city building of the research institute there is a portal between the worlds of people and evil spirits, which periodically drop in to visit. Werewolves, witches, mermaids and other "tourists" from the dark world are looked after by employees of the secret organization "Border of Worlds"
