From transvestites to transformers, we will follow the trail that will lead us in different and famous Parisian music-halls, such as the mythical Alcazar of Paris, La Grande Eugène. Whether they are below or beyond their character, often these men who are looking for themselves look at life with the humor of despair. Why this need to "transform" themselves?

Interpretations of famous characters such as Diana Ross, Josephine Baker, Billie Holiday, the Peter Sisters, the Andrew Sisters, Zizi Jeanmaire, Judy Garland, Sarah Bernhardt, among others, contribute to making this musical document an essential testimony of this era.
