Mademoiselle

As the film begins, Mademoiselle is shown opening floodgates to inundate the village, so there's never a moment in the film that the audience believes she's a normal upstanding citizen, as the villagers do. But the film provides little insight into her motivation; she has no cause for revenge, and acquires no material gain or increased standing in the community from her furtive crimes. Later, she sets fire to houses and poisons the drinking troughs, causing the death of farm animals.
