A cheap boarding school near Paris is run by tightwad headmaster Michel Delassalle (Meurisse). The school is owned by Delassalle's sickly wife Christina, who is also a teacher. Christina has a heart condition which prevents her from performing her wifely duties, so Michel has taken to banging the blonde Nicole Horner (Signoret), another teacher at the school. The prospect of Nicole becoming Michel's mistress has no effect between the two women since Michel is verbally abusive to both of them and woman beater to boot. They both despise him.
Nichole concocts a plan to off Michel. Christina, is indecisive at first, but after more rounds of abuse from Michel agrees to the plan. Threatening divorce, Christina leaves the school, drives with
Nichole to Nichole's hometown Niort and stays at her apartment. This lures Michel away from the school in pursuit of his meal ticket. Using a sedative mixed into a bottle of Johnnie Walker scotch she gets Michel to drink it. Michel passes out. Nichole and Christina carry him into the bathroom and drown him in the bath tub. Hiding his body in a large wicker basket Nichole and Christina drive back to the school and dump Michel into a disused swimming pool. They figure that once the body floats up to the top it will look like an accident.
Of course the body never floats to the top and everything goes exquisitely Noirsville.
One of the best French Noir, screencaps are from the Criterion DVD. 10/10
