The film is about morning preparations, the way to school, and school celebrations on the occasion of the Day of Knowledge. The filming took place at two-year intervals: In 1969, the elder sister Uliana was going to the first grade of the Krushelnytska Music Boarding School, and in 1971, she was already helping the younger sister Marta to get ready. The second part is full of comic and artistic techniques during the filming of the girls' waking up, exercising, and putting on their school uniforms.
