2010 год. Kasia wishes that she and her mum hadn't moved to the UK – she misses Poland and all her old friends, and most of all she misses her grandparents. As the long school holidays stretch out in front of her, Kasia wonders how she'll fill them: her mum has promised to take her out for some day trips, but the rest of the time she'll be at work. Then Babcia and Dzadek arrive for a surprise visit, and Kasia is delighted! As she proudly shows her grandparents round her new town, Kasia realizes that maybe she's happier here than she thought.
