Tam Tam (1976)

At a very camp party in Paris, guests are told about a strange tom-tom played by an Andalusian gipsy, himself a character in a book by a young novelist present at the party. A frantic quest begins for a mysterious love-filter.
Tam Tam shows desire and repression through the subversion of archetypes both social (ambassadors, stars, artists) and sexual (homophiles, transvestites, transsexuals), and converting these into a most accurate account of a certain kind of unease: an identity crisis.
