Though he is a homosexual, he has been completely circumspect in his behavior since he entered the French diplomatic corps. However, in this film, he is routinely being followed so that a dossier can be created on him by an undercover agency. They use the leverage they gain in this manner in a variety of ways, and it could even be that their investigation is fully sanctioned by the government. However, as the lad grows aware of the investigation, his carefully composed facade begins to crumble.
