Two maids rehearse killing their mistress
Sisters Claire and Solange, maids to Madame, stage a nightly ritual in her bedroom while she is out: one plays Madame, the other plays the maid, trading insults and adoration until an alarm clock warns them she is coming back. Their real plot is to have Madame's lover jailed through anonymous letters and then to poison her tea, but when he is released and Madame leaves without drinking, the plan collapses. In the final round of the game Claire, playing Madame, orders Solange to serve her the poisoned tea and drinks it.
