A story of Karel Jaroš, an emotionally arid man, whose mother suffers from Alzheimer disease. It is not love, but the sense of duty that stops him from sending his mother to a mental institution. On the other hand, this way he can finally connect with her. And not just with her but also with his teenage son and with himself.

Lenka is a high-earning manager in the global finance sector. She lives for her work and is on the verge of achieving success in her life: if she manages to close a deal with a Turkish company, she will become the director of the company for the whole of Asia. However, because of her work, she neglects her loved ones—her husband Jiří, a university professor, and her teenage son Patrik, who is currently experiencing his first relationship. A foolish bet with her son that she can skate more than 100 meters on roller skates proves fatal – she wins the bet, but immediately breaks both her wrists.

A small town somewhere in the north. The body of a brutally murdered young girl, Anna, is found by the river. The investigation is taken up by the determined criminalist Laura Linhartová (Kristýna Ryška), and her old colleague Adam Beneš (Kryštof Hádek) is assigned to her. The main suspect is a recently convicted perpetrator who is responsible for a similar murder. Just when it seems that the search for Anna's murderer is over, new evidence appears that brings the whole case back to the beginning. The criminalists thus embark on a complicated investigation full of unexpected twists and turns. The circle of suspects in the small town expands dramatically. The tension between Laura and Adam rises, not to mention their different characters and shared past. And the question still hangs in the air: Who killed Anna Pittnerová?
