In the middle of an unusually hot summer, Eliška moves back to her husband’s native village with her young daughter Karolínka. Their return is associated with a mystery that everyone seems to be aware of except the girl. The heat starts to become unbearable, the tension mounts and Karolínka begins to sense that something isn’t right. But her mother is increasingly cagey about answering her questions and is also getting increasingly wound up. The phantoms launch their attack and it makes no difference if they’re real or not. Fighting them is arduous and it’s not clear how things will turn out.
