A quiet town. People who know each other well. Soothing nature. But are you sure? Szczepan comes to Zwierzyniec for a psychological consultation. His charge is a boy who suddenly closed himself in his world, and his worried parents do not know how to reach him. The psychologist starts observing the family and expects no surprises in a sleepy and quiet town. Meanwhile, each day brings a new, disturbing discovery. Old things and wrongs are revived. Szczepan is no longer sure who he should be watching, especially when Ula - a resident of the city - starts telling him local stories, and the boy insists more and more often that he saw a scary aquarius by the lake.
