Taya and Filya are first-year twins who couldn’t be more different. Goroshok is their youngest brother, aged four, whose endearing and innocent manner charms everyone around him. While their parents are at work, the children are looked after by their grandparents, and they spend their free time in the garden with their friends Dana and Varya.
Ordinary games and household chores easily turn into adventures. The children look after their pets, conduct scientific experiments, come up with new activities and learn to understand one another. The world around them becomes a place of discovery, where even a small event can turn out to be significant.
