The composition includes two short stories: "The Swineherd" (based on the fairy tale by H.C. Andersen) and "Heaven and Hell" (based on the short story by P. Merime).

The plot is built around two charming sisters — a strict, wayward Galina, an assistant professor of mathematics, and a windy, frivolous student Shurochka. Despite the fact that the girls are so different, they are looking, of course, for one thing — love. The events take place in the summer pre-war Moscow and in the country where both sisters go: one in order to prepare for the re-examination, the other — to conduct math classes with the military from the Yuryev Camps located near the dacha village. Funny and difficult situations, intrigues, tears, joy — all this will be experienced by young girls on the way to their happiness.
