The doctor's loyal friends soon find themselves in Paris, where they meet Juliet. These former lovebirds had to split up under very dramatic circumstances almost forty years ago, and now Dr. Proctor has set out with the help of his old invention, the time tub, to change the course of events back then. However, he failed to return to the present, and the only thing that floated out of the bathtub where Julieta was waiting for him was a postcard addressed to Líza. So there is nothing left but for Líza and Bulík to take the bath of their lives and go to the past to help Dr. Proctor.
