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.
