Backbone(1975)

An unbearable stench makes quite wide confusion among the residents of Belgrade. The microbiologist Pavle can not remember immediately where he smelled it, but recalls the event he witnessed as a child and the smell of a burning human. A visit to the crematorium gives him the assurance: The high number of suicides in the city has meant that the ovens are in continuous operation and will probably stay that way - because the stench is slowly making other people commit suicide, too.
