Last Year's Quadrille

Energy students Jura, Lena and Zhanna are practicing in the village. At the dances in the house of culture, the guys notice a pretty girl Tonya, who perfectly dances a quadrille, and begin to take care of her on an argument - whose will he take. Tone obviously likes Lena. And Lena would probably win the argument if he hadn't forgotten about it, because he really fell in love.
