A mix-up of names and people causes initial confusion with the moving of a very bulky musical instrument, which – together with the recently broken elevator – provokes the residents of an ordinary apartment building to unprecedented activity. It gives the young people an opportunity to make a postponed date, it teaches a joker a lesson, it gives quarrelsome neighbors an excuse to unleash passionate exchanges of opinions... Only Mrs. Careful and her charming Chikita cause trouble and grief – both lose their grooms in their own way.
