At the margins of a city somewhere in the south of Europe, a young couple start their day with their job routine: collecting deceased pets from their owners in order to cremate them and return their ashes. This paid job aside, they also collect and cremate roadkill found as they drive around in their car, which also seems to be their home. In this endless life cycle, human beings and animals coexist harmoniously, until the couple causes a roadkill themselves.

Set against a visually stunning and desolate landscape with an eerie sensuality, Kala azar is a film about death and life itself.
