An interventionist documentary showing the phenomenon of widespread prostitution, maintained in the style characteristic of the "black series" of Polish documentaries of the mid-1950s. Staged shots at the Polonia café are juxtaposed with a documentary recording of arrests conducted by the police among Warsaw prostitutes and interrogations of the arrested.
