Four university history professors are preparing a dinner party for friends. Remy is married, Claude is gay, Pierre has a steady girlfriend, and Alain is a confirmed bachelor. The four of them have a lively discussion about sex while preparing the meal. Their guests are Louis, Dominique, Diane, and Danielle, who are waiting together at the gym, also talking about sex. Later, they all gather for dinner and resume their discussions. A portrait of two groups, men and women, from high social and cultural backgrounds, talking about sex: their fantasies, their frustrations, their intimacies, and so on. One of the great successes of Canadian cinema in the 1980s.
