Le Feu Aux Levres is a French drama about the determined efforts of the wife of a sex researcher to reveal her husband's hypocrisy and get revenge for his humiliating behavior to her. At the beginning of the film, the husband is reading humorous letters from the sexually frustrated to an informal gathering of sex researchers. One of the researchers is playing "footsie" with the wife, and she leaves the meeting with that fellow and has sex with him while the meeting continues. Her husband discovers them together, and humiliates her. She later picks up a yellow journalist at a porno cinema, and after sex, persuades him to research the foibles of the men around that table, so that she can do a little humiliating of her own. This film, with its many sexual situations, was considered to be softcore porn at the time of its release though it is rather tame by more recent standards.
