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.
Lieutenant Alan Kreiner tries to obtain evidence of criminal activity through an informant. However, when his boss is shot with his gun, Alan is accused of the murder and must prove his innocence.
