Belgrade, the capital of Serbia, only became a metropolis when it got its first serial killer: a big, fat, shy, mother-fixated man, played to deadpan perfection by one of Serbia's greatest comedians, Tasko Nacic.
He lives with his cruel mother in a gothic apartment resembling those from Mario Bava's films. He sells flowers and lives by the motto, 'Those who don't like carnations don't deserve to live!'
His victims are the young women who humiliate him in public and refuse to buy his flowers. The film follows the exploits of three main characters: the strangler, the incompetent and highly neurotic inspector on his trail and the nerdy rock singer attracted to the killer's exploits.
The latter's Oedipal desires and sexual angst turn him into a promoter of the strangler's crimes (through a song devoted to him) and a potential strangler in his own right.
