The film was banned in Poland for seven years due to realistic depiction of the life in the suburbs of Lódz as well as portraying in it local authorities, who rush the lead character into unhappy marriage.
Actress Malgorzata Potocka was set to play the role of Halina, but she then left Poland for a while and was eventually replaced by Malgorzata Pritulak.

是捷克新浪潮中最激进的一部影片，因为结尾处一群学生冲破警察的管制冲向夜色里的街头暴动场景而被迫在当年未能完成，直到1990年解禁后才由导演Hynek Bocan继续剪辑完成了影片。
A young teacher is sent to a rural re-
form school, where he is faced with
brutality of the inmates. He ends up
paying with his life for his attempts to
reform the abnormal conditions he
finds there. The story, based on the novel
of the same name by Karel Misafi, was
banned during the final editing of the
film and was only finished and releas-
ed after the Velvet Revolution.
The director Hynek Boãan (b. 1938)
avoided persecution during “norma-
lization” by shooting harmless come-
dies and fairy tales. After the Velvet
Revolution he became one of the most
productive directors of television se-
ries. He was responsible for the conti-
nuation of the popular television se-
ries “Nemocnice na kraji mûsta po
dvaceti letech” [Hospital on the Edge
of Town After 20 Years] dealing with
the fates of doctors and their patients.
At the present, he his making a series
about the lives of famous ice hockey
players on the decline.
