Katja, a young girl from Germany, finds a letter in Welsh sent to her great, great grandfather by a friend from Wales while she explores her mother's papers. To learn more, she visits Wales during the National Eisteddfod in Llanrwst. As the letter leads her to the slate-quarrying area of Blaenau Ffestiniog, Katja learns more about family's life and secrets.
