A middle-aged couple Alice and Paul have invited their best friends, Laurence and Michel to dinner. But Alice is about to cancel. While shopping, she saw Michel kissing another woman. Now, she is in doubt as to what to do. Should she tell her friend everything or should she pretend that nothing has happened? Suddenly, the guests arrive…What to do? From this constellation Zeller develops a sophisticated comedy in which it is not just about finding out who was with whom, where and when, but also about how to figure out how much truth there is in a lie. Is a lie proof of decency, friendship or even love? This is a sophisticated text with sparkling dialogues and fine parts.
