A Flea In Her Ear begins when Madame Chandebise decides to entrap her suspected husband by sending him a perfumed letter supposedly from a mysterious female admirer suggesting a rendezvous at the Hotel Pussy Cat. The wife has chosen this improbable meeting place because a package has just come from there addressed to her husband, and when she opens it (by mistake, of course) she discovers his suspenders. Then the confusions, complications, reversals, double roles, and double meanings take off!
