From Seven to Twelve (1965)

In the first episode, Petya builds a homemade camera to secretly film a schoolyard brawl but is delighted when the fighting boys stage a fake reconciliation for his lens and then decide to form their own amateur film studio. In the second, football fans Borya and Alik adopt a stray black kitten, whose presence brings victory to their favorite team. In the third, Tolik and Dima, caught in the rain in their new silk parade uniforms, take refuge in a stairwell, proving that dedication sometimes means making the best of a soggy situation.
