Antonín Kachlík wanted to make committed films about the moral dilemmas of the working class, but in the era of normalisation, he could only proclaim how faltering individuals would eventually come to the desired thinking. This is also true of the adaptation of Jiří Švejda's book about the wavering career of a young brickmaking technologist - the simplistic drawing of characters and plots, the posterishly lifeless language and the textbook discussion of social ills are all objectionable; the ideal becomes the code of the socialist builder.
