The summer holidays are approaching and the children are bragging about all the exciting places they are going to visit during the long-awaited two months of summer. Only Tonda is not looking forward to staying in Prague over the holidays. He brightens up after his father announces that the boy can visit some friends of the family in the village of Petipas.
Unfortunately the movie Three of Us and Dog from Petipas is not yet available on HBO Max.
