Schoolboy Kirill thinks he has only one flaw: he wears glasses. That's why every time he meets his girlfriend Aïna, he hides them in his pocket and assures her that he forgot them at home. His mother thinks his flaw is that he always says what he thinks. But Kirill doesn't quite agree. One day he meets a real friend, an old watchmaker who fought in the Second World War. He will be very surprised and happy to learn that Aïna is his granddaughter.
