Synopsis: Punctuated with humorous sketches, archive, events and interviews with specialists, a dive into the heart of a dark side of language : insult. Insult is a linguistic and behavioral phenomenon listed in all idioms and cultures. She emerges wherever men meet, confront or clash. From the media to the schoolyards, from the political arena to football fans, from the Internet to the world of work, it's a language barometer that reveals taboos, the tensions and norms of a society. Linguists, sociologists, psychologists or historians, some have dared to insult or insult their field of research. News Archive, feature film excerpts, small animations or comic strips echo the interviews of these experts.
