What led a former top scientist to rob a bank and hold a dozen hostages? Czech Television's crime thriller based on Martin Goffa's novel "The Little Girl" is squeezed into two environments - the interior of a robbed bank with hostages and the interior of a crisis management car, from where the police communicate with the mysterious attacker and try, like him, to play for time and find out more about him. The flashbacks also tell the story of the attacker's daughter Karin from the recent past, gradually revealing a connection with what is happening in the current storyline.

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.
