The Homolka family celebrates a great occasion: they were finally able to buy a car. They immediately begin to drive for small trips to Hradcany, to the airport, and plan further trips. Their euphoria is spoiled by a letter from their great-grandmother. Their great-grandfather is dying and the family is expected to come along to say goodbye. The annoyed Homolkas therefore set off to the South Bohemian village where the grandparents live.
