A look back at "La Cage aux Folles", which ran non-stop for five years, from February 1973, on the stage of the Théâtre du Palais Royal in Paris. At a time when homosexuality was considered a crime by the law, Poiret and Serrault achieved great success in boulevard theater. Their success continued on the silver screen, with three Oscar nominations and a Broadway musical. Combining never-before-seen archives from the play, extracts from the film, confessions by Poiret and Serrault, and interviews with witnesses, this is the story of a wild epic.
