A Horseman over the City(1967)

Schoolboy Kirill has only one flaw—he wears glasses. So when he meets his classmate Aina, he hides them in his pocket and, whenever she asks him about them, he claims he forgot them at home. Meanwhile, Kirill's mother believes that his only flaw is that he always says what he thinks. However, their points of view are not entirely different. One day, Kirill will find a true friend — an old watchmaker who fought in World War II. The boy will be surprised and delighted to learn that Aina is his granddaughter.
