A Flea in Her Ear is the greatest of French farces, perhaps the greatest farce ever written. Set in Paris, the story centers around the comical misunderstandings between husbands and wives, lovers and friends. Believing that her husband is conducting a secret affair, Raymonde Chandebise devises a trap in the form of an anonymous love letter to catch him in the act. Soon the letter makes its way through their group of friends, setting off a chain of hilarity that includes shameless jealousy, mistaken identities, and lots of door slamming.
