A classic production film made in line with the rules of socialist realism. An outright work of propaganda using patterns typical of action cinema, spy films and melodramas, as well as referencing ideas propagated by the party, such as the need for constant vigilance and social advancement of women. The script was written by Adam Ważyk, a staunch advocate of communism in the post-war years who during the post-Stalinist thaw became one of its main critics, which he expressed in his famous "Poem for Adults".
