Every family has its traditions. Some also have secrets.

The life of little Theo passes in a slow, killing rhythm. His aloof and reclusive mother educates him at home and instead of taking him for walks, she takes him to a community religious center. Under the tree, Teo always finds only another part of Kája Mařík. And father disappears somewhere every Sunday afternoon. However, growing up cannot be stopped, and so even Teo's sad routine with starting school and a new friend is getting its first cracks. And with her the whole family situation, surrounded by silence, mystery and sadness. The older Teo gets, the more he withdraws from his family. But even his own independent life is ultimately anything but satisfied: there is an empty place in it that needs filling.

Sunday Afternoon is a story about the troubles and tragedies of one family, told from three perspectives. What may seem crazy to a son suddenly makes sense from a mother's or father's point of view. It is a book about passing each other and getting closer.
