The residents of the apartment building on Rue Montmartre are a motley crew of oddballs and eccentrics. The daring son of a professor couple is in love with a sexy student who supplements her pocket money by working as an au pair. And then there's Monsieur Calomel, the crazy but helpful neighbor who's always ready with a funny face...
