Thé à la menthe ou t'es citron ?

It's the story of a troupe of actors rehearsing a boulevard play about a gentleman burglar who breaks into the home of an aristocrat. It's all there: the cuckold, the lover in the closet and the expected misunderstandings.
But nothing's ready yet, with a director overwhelmed by the situation, a lead actress on the verge of a nervous breakdown, an old fuddy-duddy with a penchant for gags, a young lead who's a novice, clumsy and a blunderer, but the producer's son, a stagehand who's off her rocker, and an actor who's always coming up with new ideas for his character - it's quite a team!
The evening of the premiere arrives, and then... all hell breaks loose, with one unforeseen event following another in dizzying madness.
