The summer of 1955 is extremely hot. Ten years is not enough to rebuild the torn down capital, but enough for an unconscious child to become a young woman. M is on the threshold of adult life. It's an important moment of her life. Soon she'll receive her final high school diploma, lose her head over K, come to understand what ZMP (Union of Polish Youth) means for her and face college entry exams. On hot days, it's easier to believe in the Thaw.
The story of M touches the topic of puberty. During this period, the emotions are invariably complicated. The only thing that changes is the scenography.
