Technical school student Pavel Brychta, arrives at a youth correctional facility located within a chateau in Konečno. He is an atypical, but not hopeless case for the institution. Pavel comes from a well-off family and his antisocial behaviour on the verge of criminality was some kind of response to his difficult relationship with his authoritative father. However, it takes quite some effort for Pavel to find his place in this environment of bullying, and also diverse methods from the tutors
Thieves Svarc and Cihák are interrupted in their robbery of a jeweler's store. In order to disappear as quickly as possible, they jump into the nearest car and leave, finding on the way that a little boy named Jirka, son of the car's owner, is with them. They take him to a cottage where Cihák's eighteen-year old daughter Milena attends to him. Jirka first treats Milena with hostility, but as days pass, the "prisoner" and the "guard" become close. Milena cooks for the boy and takes care of him, but nothing can intimidate the dauntless Jirka and he seeks for the first opportunity to escape.
