France 1871. The Paris Commune is settled. The government’s army is determined to put an  end to the Commune. In that violent situation, some bodies are found in the streets of Paris; the skin has been pulled off and the blood has been taken away. The government of the Commune has chosen the scientist Sophie Blanchet to investigate these chilling murders. There are two men under her command: Fabian, a young revolutionary; and Leo, a man who after spending ten years in a Polynesian jail, works for the Commune.
