The protagonist of the story, which is set in Finnish Lapland around 1950, is a man by the name of Gunnar Huttunen, who settles in a small village to mend and run a derelict mill.
Huttunen is an enterprising and resourceful man, a hard worker, proudly independent but generally good-natured.
However, his peculiar personality, particularly his habit of howling to vent his emotions, turns the intolerant villagers and authorities against him, and he is eventually committed into a mental hospital.
After escaping, Huttunen lives as a fugitive in the wilderness, aided by his few friends: his lover Sanelma, the local police constable Portimo, and the postman and moonshiner Piittisjärvi.
It has twice been adapted into a feature film: a Finnish one called Ulvova mylläri (1982) and a French one, Cornélius, le meunier hurlant (2017).
