Desiderium lyrically charts the hapless loves of three brothers: Majid, the young handicapped brother with a deformed head who falls in love with Aghdas, a prostitute hired by his eldest brother Habib to entertain him, not knowing the truth about her profession. Karim, the middle brother is so infatuated with a quail that he almost completely ignores his wife and her emotions. Habib himself is in love with Foroogh, a tailor lady who lives with them, while his sense of responsibility about Majid keeps him from requiting her affections.
