Jodelet holds from Nise, the maid he loves, love secrets of several suitors and their beauties and since "the language of a valet is worse than a trumpet", but the secrets are soon disclosed.
The unfortunate Nise is ruthlessly hunted by her mistress, but Jodelet has more than one trick in his bag and saves the day: he says he is an astrologer and claims to hold from the revelation of the stars everything Nise told him.
The comedy becomes a satire against astrologers and soothsayers who retailed their nonsense to Parisian onlookers.
