Оливка, Игорёк и Рекс

1980s, USSR. Seven-year-old Olya, whom everyone calls Oliva, grew up in the village. By her side is always her faithful friend, the shepherd Rex. Olive is sure that she understands animals and easily finds a common language with them, be it a dog or a goat. In addition, Olive is a very erudite girl with a precocious adult view of the world, because she accidentally read her grandmother's entire library. Her best friend Igor is a moderately quick—witted, but very economical and wholeheartedly in love with Olive, a boy who is ready to support any of her adventures.
