Hatan in Pajamas.

Somewhere in a holiday home in France, Bernard and his wife Jacqueline are expecting guests for what promises to be a pleasant weekend. One of the guests is Bernard's best friend Robert, who is Jacqueline's secret lover. The other guest is Brigitte, Bernard's secret lover. The master of the house tells his wife that Brigitte is Robert's partner, but since Robert has never seen the woman before, he mistakes her for the maid, who is also called Brigitte. And if all that wasn't enough, the maid's husband, Bertrand, will soon set her up for a "kiss".
