"Ptaszysko" is a short, semi-surreal impression based on a fragment of Janusz Glowacki's book "Good night, Dzerzi". The focus of the film is the relationship between the main character, Kosinski (whose identity is barely suggested), and the Polish cleaner. An irregular tangle of events crossing in one place and diverging in another outlines the character of the protagonist, melting and unspecified in unambiguous assessments.
